Holly Willoughby 'calls out' pal Emma Bunton during interview at KSI ...

Holly Willoughby has surprised fans after calling out good friend Emma Bunton at KSI's boxing match last night. The 29 year-old YouTuber, named Olajide Olayinka Williams, fought Faze Temperr on Saturday in London's Wembley Arena.

KSI came out victorious, beating his opponent in less than two minutes. Many famous faces came out to watch the match, with the ITV presenter among them.

While fans were taken aback to see Holly ringside, they were further stunned when she "called out" former Spice Girl Emma Bunton as she spoke to the cameras. During a bizarre interview, the This Morning host decided to slam pal Emma, who passed on the chance to watch the fight live to stay at home with her kids, reports the Mirror.

When asked who she would like to "call out", Holly Jokingly responded: "Do you know what? I know one of my very good friends, who is normally on stage in here - Spice Girl Emma Bunton - is watching this at home with her son Beau. So I'm calling her out you, Emma Bunton."

After being left in disbelief by Holly's attendance at the boxing match, Twitter users are now calling for a fight between the This Morning star and her close pal, Emma, after they jokingly claimed there's "beef" between the two stars.

"Never thought I'd see the day where Holly Willoughby would be ringside!!!!! What is going on!! Fight between her and Emma Bunton," one Twitter user joked. "FIGHT FIGHT FIGHT! Holly and Emma are next," another echoed.

Someone else quipped: "Ummm I had to switch off the telly and back on again because I thought I was seeing things! Holly Willoughby at a KSI match. Ain't no way hahaha." While a fourth tweeted: "Ooooooh I bet Emma will be happy with that! Who knew all these women liked boxing so much."
