A modern family! Brandi Glanville gushes her son is 'soooo handsome' as she poses with the teen before prom as does dad Eddie Cibrian and his wife LeAnn Rimes

Brandi Glanville and Eddie Cibrian's oldest son, Mason, went to prom this weekend, and the proud parents were joined by Eddie's wife Leann Rimes for the celebration.

The Real Housewives Of Beverly Hills star, 48, commemorated her 17-year-old son's milestone with two Instagram posts that she shared on Saturday.

'Prom night!!! Omg my baby looks soooooo handsome!' she gushed in a caption of the first post featuring a photo of herself with Mason.

In the photo, Brandi is casually attired in a white sweatshirt and orange sunglasses as she beams with pride and wraps her arm around her son.

Mason, who was clad in a black suit with a crisp white button-down shirt and a black tie, smiled widely at the camera. 

Glanville shares Mason and younger son, Jake, 14, with her ex-husband actor Eddie Cibrian, 47,  who was also on hand for the festivities.

One of the photos that Brandi included in the slideshow of her second post featured Eddie, in long-sleeved white shirt and black pants, as he grins at the camera with Mason, who glances to the side with a smile.

Cibrian was holding a camera with a long lens in the shot while Mason clasped a box with a white rose corsage in pink tissue paper.  

Eddie and Brandi famously split in 2009 after eight years of marriage when it was revealed that he was having an affair with singer LeAnn Rimes, 38.

LeAnn and Eddie began their highly-publicized affair while co-starring in the 2009 Lifetime movie, Northern Lights. The How Do I Live singer was also married at the time to backup dancer, Dean Sheremet, 40.

The affair led to the Brandi and Eddie's divorce which was finalized in September 2010. LeAnn and Dean also parted ways in June 2010. 

Eddie and LeAnn became engaged in December 2010 and married in April 2011. Though Brandi and LeAnn initially had a contentious relationship in light of the affair, over the years, they have become friends.

The reality star and the country singer have been spotted attending Mason and Jake's soccer games together and celebrate the holidays, including this past Christmas and Easter, as a family.

On Mother's Day this year, LeAnn and Brandi appeared in a photo with Eddie, Jake, Mason and Eddie's parents, Hortensia and Carl, which both ladies shared to their Instagrams.

Leann simply captioned the photo 'Happy Mother’s Day! #mothersday2021 #mothersday' while Brandi wrote , '#ModernFamily Today was a great day. I love this crew (honestly),' adding a heart emoji and two crying laughing smiley face emojis.

Glanville also included a photo of Leann who was there to join in the fun on Mason's big day. In the shot, she is seen posing with her stepson while wearing a long black skirt with a high slit, a black leather jacket and white shirt that appeared to aptly read 'I'm here.' 

Other photos in the slideshow included Mason presenting his date, who was wearing a long lacy black dress, with her corsage and the pair smiling in another snap.

Mason also posed in a solo snap and with one of his friends in another. Brandi also included a couple of group shots featuring the teenager with his high school friends.
