Apparently celebrity couples have chosen this weekend as vow renewal weekend. Wouldn't you know it, the two couples who decided to actually participate are two who also love publicity. LeAnn Rimes and Eddie Cibrian renewed their vows Friday because after a year you really need to remember why you got married in the first place and Nick Cannon and Mariah Carey renewed theirs in Paris for the fourth time. There have been rumors that Nick and Mariah were having some marital strife so perhaps this vow renewal thing was their way of making those rumors go away. Also for Mariah to get some press and do some shopping and to have another party. I think they do it so often because Mariah likes to feel like the center of attention and being a bride every few months is her way of making that happen.
