Kim Kardashian looks tense after Pete Davidson leaked bedroom snap and text exchange with Kanye West

Kim Kardashian appeared tense and glued to her phone on Sunday as her public feud with ex-husband Kanye West reached new heights when boyfriend Pete Davidson finally hit back at the rapper.

The Hulu reality star attended a sports game for her son Saint, six, and was accompanied by daughter North, eight, both of whom she shares with Kanye. The former couple also share Chicago, four, and Psalm, two.

However, while Kim, 41, was on the playing field, it was all kicking off between Pete, 28, and Kanye, 44, as leaked text messages exposed a heated exchange.

The mother-of-four, dressed casual in athletic wear and a pair of Pete-approved Vans sneakers, seemed to be dealing with the fall-out of it all as she looked preoccupied with a tense phone call throughout the day.

As Kim was pictured, her nasty battle with Kanye erupted when it was revealed that Pete had sent Kanye a shirtless snap of himself, telling the rapper he was 'in bed with your wife.' 

Pete also referenced the sports day with Saint in the messages, as he urged the rapper to meet 'man to man.' 

He wrote: 'Why don't we meet after Sunday service and saints game... I'll be at the BHH [Beverly Hills Hotel] we can have food and talk it out in my room. Privately one on one. Man to man.'

Kanye had previously referenced the game in one of his videos, where he said he had moved his Sunday Service to attend.  

But it's not just Pete who is breaking his silence - as on Monday, Kim made the rare move of responding to Kanye's ongoing social media attacks against herself and her boyfriend. 

Kanye posted a picture of daughter North's school backpack that had enamel pins of himself, Kim, and alien, and said 'This was on my daughters back pack when I was "allowed" to see her last week.' 

The alien pin could be viewed as a subtle reference to his claims of 'parental alienation' amid their divorce.  

However, Kim hit back in the comments: 'Please stop with this narrative, you were just here this morning picking up the kids for school.' 

Don't mess with her: Kim told Kanye on Monday, 'Please stop with this narrative, you were just here this morning picking up the kids for school'

A lot on her mind: Kim has been navigating the custody fall out for the last few months 

A TMZ report stated Monday that is not seeking a protective order against Kanye.

Per the report, they do not have a structured custody agreement - Kanye is allowed to see his children when he wants within reason - and Kim does not want to limit Kanye's time with his children. 

But as Kanye continues to claim that there is custody issues between them, it now seems neither Kim nor Pete are willing to stay silent.

On Sunday, Pete came out fighting in leaked text messages that were shared by Saturday Night Live guest writer Dave Sirus, who has previously posted on behalf of the comedian. 

'Yo it's Skete,' Pete began in the message - referencing the disparaging nickname Kanye has given him. 'Can you please take a second and calm down.'

What's going on now? Kim looked as though she was getting minute-by-minute updates of her ongoing feud with Kanye 

It never stops: Kanye has been posted disparaging messages about Pete, as well as complaining about having access to his kids, for many months now 

Kim, 41, attended a sports game for her son Saint, six, and was accompanied by daughter North, eight, (pictured above) both of whom she shares with West, 44. The former couple also share Chicago, four, and Psalm, two

'Kim is literally the best mother I've ever met. What she does for those kids is amazing and you are so f***ing lucky that she's your kids mom,' Pete went on.

'I've decided im not gonna let you treat us this way anymore and I'm done being quiet. Grow the f**k up.' 

Kanye then responded, writing: 'Oh you using profanity now. Where are you right now?'

Not staying silent: On Monday, Kim made the rare move of firing back at Kanye on social media, rubbishing his accusations that she doesn't allow him proper access to their children 

Dealing with business: Kim took an important phone call on Sunday while out with daughter North and son Saint 

Long time coming: Kim officially filed for divorce from Kanye back in February last year, and asked for joint legal and physical custody of their four children

Pete hit back sharing a shirtless snap between the sheets, saying: 'In bed with your wife.' 

The exchange comes after weeks of attacks thrown at the SNL star from the rapper - who last week got into hot water for releasing a music video showing a Pete lookalike getting buried alive.   

Most recently, Kanye has been releasing a series of videos over the weekend where he talks about his custody issues with Kim. 

Meanwhile, Pete Davidson was seen out for the first time on Sunday after taunting Kanye West with a selfie taken between the sheets with Kim Kardashian

'Hey everybody, I just got off the phone with Kim. I told her to stop antagonizing me with this TikTok thing… I am her father. I know y'all don't respect fathers,' he said in the video. 

'I said I'm not allowing my daughter to be used by TikTok, to be used by Disney. I have a say so. And then when people say "oh, they're going to use this for you in court"…there's no such thing as 50/50 custody in society today. It always leans towards the mom,' he added. 

He then claimed in the caption that North wasn't allowed to go to his Donda 2 album party or to a basketball game with him. 

He also claimed none of his children are allowed to attend his Sunday Service. Kanye added: 'Saying a prayer that my children can come to Sunday Service.' 

Here we go! Pete Davidson finally addressed Kanye West's never-ending social media attacks aimed at his girlfriend, Kim Kardashian, and her parenting choices in a text exchange shared to Dave Sirus' account on Sunday morning

Kim officially filed for divorce from Kanye back in February last year, and asked for joint legal and physical custody of their four children. 

At the time, sources close to the former couple said both Kim and Kanye were in agreement about this. 

In the following months, the pair seemed as though this would be an amicable split, as Kim continued to support Kanye by being a part of his Donda album campaign. 

Talk about it: The 28-year-old comedian, who has used Dave's account in the past — recently to share a few kind words following the death of comedian Bob Saget — demanded Kanye take his public battle somewhere else and meet him 'face to face' instead of airing dirty laundry

'What you are doing to your family is dangerous and going to scar them for life,' Pete told Kanye. 'Please handle these matters privately bro I beg you'

In August last year, Kim even wore a Balenciaga Couture wedding dress to appear on stage at a listening party in Chicago.

At this point, Kanye had already appeared to move on romantically as he was spotted on dates with Russian-born supermodel Irina Shayk.

However, it seemed that things turned sour between Kanye and Kim when she began her relationship with Pete late last year.
