LeAnn Rimes and Eddie Cibrian renew their wedding vows

It's been a year since one of Hollywood's biggest unions became official -- no, not the Royal Wedding; LeAnn Rimes and Eddie Cibrian. To honor their first anniversary, the couple renewed their vows and later took a trip to the place where they tied the knot in 2011.

"Renewed our vows today....it's incredible to thank each other for the past year as husband and wife. Here's to another great year!" Rimes tweeted April 12.

The following week, the couple revisited the Malibu location where their wedding ceremony was held. "We chilled & ate cake under the tree where we got married," Rimes posted April 23 along with a photo of the site. The couple had a mini replica of their wedding cake made for the occasion.

"We have had the most wonderful first anniversary weekend in Malibu. We stayed at the house where we got hitched. We spent time w/ the boys, our friends and we saw our families....it was perfect and relaxing. Few more days til we go away for a lil bit, just the two of us. The first year deserves two weekends :) we feel really blessed. Hope you all had a fabulous weekend yourselves," Rimes writes.

And if that wasn't enough celebration, Rimes and Cibrian jetted off to a tropical location for another weekend of celebrating their marriage.
