HGTV's Tarek El Moussa sparks romance rumors with reality star -- who looks like ex, Christina Anstead!

Moving on!

Tarek El Moussa, who co-stars on HGTV's "Flip or Flop" with ex-wife Christina Anstead, sparked romance rumors over the weekend when he was photographed making out with another reality star.

In photos published by TMZ, the 37-year-old reality can be seen hanging out on his boat in Redondo Beach, California, on Sunday, alongside Heather Rae Young, who is one of the real estate agents starring on Netflix's "Selling Sunset." The pair was also photographed making out in several of the photos.

During their Sunday boat ride from Newport Beach, the rumored couple was also caught on camera on one of their pal's Instagram Stories. Upon doing some digging, there are signs that El Moussa and Young have been flirting online since early July, as the "Flip or Flop" star has been commenting flame emojis on several of the Netflix star's photos.

It's also hard not to notice the physical similarities between the new woman in El Moussa's life and his ex-wife, Christina Anstead.

Christina and Tarek had a contentious split in December 2016, but have since patched things up. The former couple, who share daughter Taylor, 8, and son, Brayden, 3, still star on "Flip or Flop" together. In fact, season 8 premieres on Thursday, August 1. They have also both branched out into their own solo TV projects.

Christina has already more than moved on from her ex: She married British TV personality Ant Anstead in December 2018 and announced in March that she's expecting her first child with her new husband.
