A source told PEOPLE last week that Haack's solo home renovation show 'Christina on the Coast' was not renewed for a new season

HGTV Star Parties With Ex-Husband and New Boyfriend for 42nd Birthday originally appeared on Parade. Christina Haack celebrated her 42nd birthday by partying in Las Vegas with her new boyfriend, Christopher Larocca, as well as her first ex-husband, Tarek El Moussa, and his wife, Heather Rae El Moussa.

HGTV officially pulled the plug on Christina on the Coast after five seasons, part of a broader programming shakeup at the network. The Flipping El Moussas, starring her ex-husband Tarek El Moussa and his current wife Heather Rae, was also canceled after two seasons.

On Monday, July 7, the HGTV star marked her upcoming 42nd birthday by posting a bikini photo of herself along with a reflective caption on Instagram. Haack — who turns 42 on July 9 — was snapped sipping on a glass of bubbly while relaxing poolside in a black chain-link bikini on what appeared to be a vacation.
