(Cover) - EN Showbiz - Mike Tyson has tied the knot for the second time in two years after renewing his wedding vows in a surprise Las Vegas bash.

The former heavyweight boxing champion said "I do" to his wife Lakiha again in front of hundreds of family and friends who had gathered for what they believed to be a joint birthday party.

After greeting their guests, the couple disappeared before re-emerging behind a large curtain which opened up to reveal them dressed in wedding attire.

The surprised crowd then witnessed the couple renew their vows in a traditional Muslim ceremony before partying the night away in the hotel's ballroom which was outfitted with a live band.

The couple had a very small wedding in a Las Vegas chapel in 2009, but it was a somber affair as it was just two weeks after Mike's four-year-old daughter Exodus passed away after a freak accident on a treadmill machine in his home.

Mike has said after marrying his third wife he follows a more simple existence and is happier than ever.

Mike, who turns 45 on June 30, spoke to Ellen DeGeneres earlier this year about how he has improved his lifestyle in the past two years including living a sober life and following a vegan diet. (C) Cover Media
