Mike Tyson and Lakiha SpicerBoxer Mike Tyson and his wife Lakiha Spicer have renewed their wedding vows in a surprise ceremony.

TMZ is reporting that Tyson and Spicer invited hundreds of their friends to celebrate a joint birthday party the couple were throwing for each other at the M Resort in Las Vegas last week - Saturday June 25, but in reality the birthday party was a cover for a secret vow renewal.

Tyson even tweeted about the fake event, "My wife & I are getting ready to host friends & family tonight. Many we haven't seen in years. It's going to be a great night."

After the guests arrived at the party, the couple disappeared for a while only to later re-emerge dressed in wedding outfits.

And then to the amazement of the surprised crowd, the couple then proceeded to renew their wedding vows in a traditional Muslim ceremony.
