Tarek El Moussa hasn’t met ex-wife Christina Anstead’s new son — yet.

While Christina and her husband Ant Anstead spent time in the hospital on Saturday with their son Hudson London, who was born on Friday, El Moussa cheered on daughter Taylor Reese at her first soccer game of the season.

Following the game, the Flip or Flop host, 38, applauded his daughter, who will be 9 this month, for scoring a goal as he shared how “thrilled” she is to be a big sister.

“My Baby girl had her first soccer game of the season today…and she scored!!!” he wrote alongside a video of the pair. “I’m sooo excited that soccer is back!!! It’s so much fun to watch her play and cheer her on!! This little girl right here makes daddy so proud! She works so hard!”

“She got to meet her new brother Hudson yesterday and she was thrilled!!!” he continued, adding that he “can’t wait to meet the little guy also!”

El Moussa went on to joke that he might be willing to look after Hudson — for a price. “If Christina and Ant pay well I may baby sit 😎” he wrote.

Proving just how much affection she already has for her little brother, after her game Taylor stopped by the hospital to give baby Hudson a cuddle, seemingly making the visit without her father.

“This cutie scored her 1st goal of the season at her first game, and came by straight after to cuddle brother,” Christina wrote on her Instagram Story alongside an adorable photo of her daughter holding her newborn son.

El Moussa recently revealed that he introduced new girlfriend Heather Rae Young to Christina without giving either much warning.

Instead of telling the Selling Sunset star, 31, or Christina, 36, that the two of them would be meeting in advance, El Moussa revealed on GMA3 earlier this week that he blurted out the news on the way over to Christina’s house.

“I was like, ‘Oh, I’m coming over to see the kids. By the way, my girlfriend is coming. See you in five!’” El Moussa recalled telling his Flip or Flop co-host over the phone before his arrival.

Despite the potentially awkward situation, El Moussa said the two “got along great,” joking that they’re both into the same “weird stuff.”

“They both eat that healthy, hippie food. That weird juice. They do that weird hiking stuff,” he said.

El Moussa’s new relationship comes a year and a half after he finalized his divorce from Christina in January 2018.

While the two remain divorced, they continue to work on Flip or Flop together, filming over 2,000 episodes to this point
