The 34-year-old "Flip or Flop" star shared a photo Thursday on Instagram from her trip to Cabo San Lucas with British television host Ant Anstead.
The picture shows El Moussa and Anstead enjoying a sunny outing at the beach. El Moussa shows a smile in a bikini as she holds Anstead's hand.
"Salty hair and toes in the sand with my man @antanstead," she captioned the post.
Anstead shared a video on his own account of himself and El Moussa making a playful wager on the beach.
"When you argue with the missus for who gets up to go get drinks! Obviously you settle it with a scissor paper stone game!! although I'm pretty sure @christinaelmoussa cheated!! She's in my head!! and guess what..... I'm the one getting the margaritas," he wrote.
El Moussa and Anstead, who is known for hosting the British series "For the Love of Cars" and "Wheeler Dealers," were first linked in January.
The pair celebrated their six-month anniversary as a couple in April.
"What an amazing six months it's been with this lady!" Anstead said at the time.
"Where has the time flown! I've loved every second I spend with her! She totally gets me (which is rare) and we have done so much in such a short time!"
El Moussa was previously married to "Flip or Flop" co-star Tarek El Moussa.
She discussed her dynamic with Tarek in a press release this month ahead of the show's return, saying filming has been "beyond awkward."
