'Boxing's baddest' Mike Tyson undone by Kiss Cam

He was once regarded as boxing's baddest, but Mike Tyson appeared nothing more than a big softie when he was caught out at the Indian Wells tennis tournament.

Tyson was sitting in the stands watching a doubles match when a break in play signalled the start of Kiss Cam and the appearance of several couples on the event's big screens.

They all obliged by puckering-up for the cameras, before Tyson's somewhat surprised face was beamed around the venue, triggering chuckles from other audience members.

The 49-year-old is probably best known for biting off part of Evander Holyfield's ear during a fight, but he's definitely mellowed in retirement.

And as if to prove the point, 'Iron Mike' hardly skipped a beat as he turned to his wife and planted a kiss on her lips, turning those chuckles into widespread applause.
