Christina Hall borrows ‘not appropriate’ red lace dress from Heather Rae Young for night out with boyfriend

These two are practically sisters.

Christina Hall tapped her ex-husband Tarek El Moussa’s current wife, Heather Rae Young, for a little date-night outfit help.

The “Flip or Flop” star chose a memorable red lace dress for the night out with new boyfriend Christopher Larocca at Mar-a-Lago in Palm Beach, Fla., Thursday.

“Thanks for lending me the gorgeous dress @theheatherraeelmoussa,” Hall, 41, wrote on a photo posted to her Instagram Story thanking Young for the semi-sheer design.

Meanwhile, Larocca matching with a red tie and all-black suit. She posted more photos with other couples as well as motivational speaker Tony Robbins and actor Russell Brand.

Fans of the extended El Moussa family will recognize the gown from Christmas, when the “Selling Sunset” alum first wore the red-hot style — and clapped back at haters of the look.

Responding to a hater who remarked that the see-through design was “not appropriate” for a mother, Young said, “so because I’m a mother I can’t wear a pretty dress that makes me feel beautiful? What does that have to do with anything? I am still a human and my name is heather I’m not just a mother. Choose joy.”

She added, “Comments like this make me laugh. I don’t even get offended anymore by the rudeness of others. I choose to spread joy not hate.”

Young and El Moussa share a son, Tristan, 2, while the HGTV star also shares daughter Taylor, 14, and son Brayden, 9, with Hall, to whom he was married from May 2009 to January 2018.

While the relationship between Tarek’s first wife and his current has been rocky at times, they seem to be the best of friends currently — and the trio even has a new show together, called “The Flip Off” that seems them compete in the home renovation category.
