Heather Rae El Moussa and Christina Haack teamed up for the ultimate bikini photo shoot.

Selling Sunset’s Heather, 37, who is the wife of HGTV star Tarek El Moussa, tapped Haack, 41, who is Tarek’s ex-wife, to star in a sizzling hot campaign promoting her newest lip gloss color, Perfect Pink, part of her Heather Rae Essentials collection.

In the shoot, the blonde beauties looked just like Barbie dolls while twinning in hot pink bikinis featuring triangle halter tops and string bottoms that tied in bows at their hips. The women leaned their backs against each other while applying the bubblegum gloss.

Heather, for her part, rocked white square sunglasses, which she teamed with a vibrant headband and gold jewelry.

Heather Rae El Moussa and Christina Hall are enjoying the last laugh when it comes to the chatter surrounding their relationship. After Tarek El Moussa marked Mother’s Day weekend by celebrating both his wife and ex-wife on social media, the entire trio reunited for a playful video.

For glam, Heather donned a full beat including brown eyeshadow, flirty lashes and, of course, her $24 gloss, which features a vanilla flavor and non-sticky hydration. She braided part of her tresses and tied the rest of her locks back into a ponytail.

Haack looked just as stylish in cat-eye shades complete with a white rim and a messy updo. Just like Heather, she glammed up her look with gold bracelets.

Elsewhere in the campaign, Heather went swimming in a gold bikini featuring a cowl neckline. She styled the number with diamond rings and a dainty butterfly necklace.

In one shot, she added even more of a summer-fun accessory with a pink visor as she applied the gloss to her pout.

Heather and Haack also made a campaign video together, where they slayed in sparkly pink heart-shaped sunglasses while tanning by a pool. They sipped on champagne while wearing coordinating black-and-white bikinis.
