LeAnn Rimes and Eddie Cibrian are officially engaged! Over the holiday weekend, the actor asked for LeAnn's hand in marriage while surrounded by close friends and family at the couple's Los Angeles-area home.

"Thank you for all your well wishes," LeAnn tweeted minutes after the news broke this afternoon (December 27). "We are extremely excited and look forward to a beautiful future. It's been an incredible last few days. I was shocked! We are blessed, our families are so happy, and our lives are filled with love.

"It was nice to have our little secret for us, our families, and friends a few days," she continued. "[We are] so excited to now share the wonderful news with our fans. It's for real this time and the first time ever!"

Monday, LeAnn and Eddie were spotted on a Malibu beach, where she was wearing her new engagement ring. According to People magazine, the platinum sparkler features a 5-carat oval diamond set in rose gold fleur-de-lis connected to the band.

Once they wed, LeAnn will become the stepmother to Eddie's two children with model Brandi Glanville, Mason (7) and Jake (3). LeAnn's divorce from Dean Sheremet was finalized this past June. Dean announced his own engagement news to photographer Sarah Silver last month, which LeAnn commented on by wishing her ex and his bride-to-be "a life full of happiness."

This will be the second marriage for both LeAnn and Eddie, who met on the set of a made-for-TV movie while they were both still married. Amist a flurry of tabloid rumors, they initially denied an affair but have since owned up to their infidelity.

"If I take away my album sales [and] my words, you have just another couple," LeAnn told ABC's Robin Roberts last month. You had two couples whose marriages didn't work who really stumbled upon each other and fell in love. Never ever was I thinking of hurting someone."

There's no word yet on the Rimes-Cibrian wedding date.
