LeAnn Rimes got super frisky with another woman on a Los Angeles beach over the weekend.

While celebrating the Memorial Day holiday with her friends and family, including husband Eddie Cibrian, Rimes was caught making out with a red-headed female friend as her hubby looked on.

"LeAnn Rimes locked up 'Wife of the Year' -- just an educated guess -- by sucking face with a smoking hot girlfriend in front of Eddie Cibrian," TMZ reported on Wednesday. "The couple was hanging in Malibu on Monday for a family BBQ, but their family fun probably looked much different from yours... LeAnn and a redheaded bikini-clad chick went on a selfie-fest on the beach, complete with full mouth kisses."

Rimes and Cibrian had quite the eventful weekend. In addition to Rimes' make-out session with her friend, Cibrian suffered a broken hand.

"Namaste! My sweet hubby broke his hand over the weekend hand while surfing. I'm playing nurse. #alwayssomething #hubbylove #broken #cast," Rimes revealed on Instagram, along with the photo below.

In other Rimes-Cibrian news, his ex-wife, Brandi Glanville, recently revealed she and Rimes' ex-husband, Dean Sheremet, were teaming up for a new cooking show.

"I am no longer married to Eddie, so I don't have to get his permission to do anything," Glanville explained to E! News when asked about her former partner's thoughts. "And vice versa for Dean."

As for their current relationship, the former Real Housewives of Beverly Hills star revealed they were all getting along -- at least for the time being.

"Yeah, we have open house tonight I'll see them there, yeah," Glanville explained. "We're good right now. It ebbs and flows. Right now, we're really good. In the past it's been really hard and bad but we're both trying right now, especially with the kids getting older, to be a proper, modern family."
