Blond bombshells Heather Rae Young and Christina Haack make a splash in bikinis for poolside shoot

Double trouble.

Heather Rae Young and Christina Haack flaunted their figures in coordinating black-and-white bikinis while lounging poolside.

The “Flip Off” co-stars came together for a Heather Rae Essentials campaign to promote the brand’s new Perfect Pink Lippie Gloss, per a video shared via TikTok Thursday.

In the clip, the duo was seen walking toward lounge chairs and popping open a bottle of champagne, while Cyndi Lauper’s pop anthem “Girls Just Want to Have Fun” played in the background.

They both smiled widely while clinking their glasses of bubbly.

Haack, 41, and Young, 37, styled their blond locks in waves and wore pink heart-shaped sunglasses.

“She’s here. She’s pink. She’s perfect. 💋,” the video was captioned.

“Heather + Christina, poolside and glowing, are giving hot girl summer meets blended beauty — and this shade is the cherry on top.”

The two ladies have grown closer over the years since Young married Haack’s ex-husband Tarek El Moussa.

The “Christina on the Coast” star was previously married to El Moussa, 43, from 2009 to 2018.

The exes have maintained an amicable co-parenting relationship for their two kids: Taylor, 14, and Brayden, 9.

El Moussa and Young tied the knot in 2021.

The couple shares a 2-year-old son, Tristan.

El Moussa, Young and Haack star together in HGTV’s “The Flip Off” and often come together for events with their blended family.

In fact, El Moussa and Young recently vacationed with Haack and her new boyfriend, Christopher Larocca, in Cabo San Lucas, Mexico.
