Chrissy Teigen is saying “I do” again to John Legend … in a bath towel. The “Lip Sync Battle” co-host is always up for a good joke, but this one takes the cake. It all went down Friday in the backyard at the couple’s Los Angeles mansion. Teigen got the bright idea to renew their nuptials after a member of her team taught her how to properly tie a shower towel around herself. Apparently the light bulb went on and an impromptu wedding ceremony ensued.
