AceShowbiz - Having mended his relationship with Christina Anstead after their split, Tarek El Moussa spoke highly about his ex-wife, but may have gone too far by dropping a juicy bit about his ex-wife's pregnancy. Appearing on "TMZ Live" Monday, April 8, the "Flip or Flop" star unexpectedly revealed the sex of Christina's baby.

The 37-year-old reality TV star admitted that his relationship with Christina was strained after their split in December 2016, "but things are good today." He went on gushing, "She's remarried, she's actually pregnant - everybody knows that."

But then he casually spilled the beans, "She's having a son." Tarek added, "My kids are super excited. I'm excited for her new chapter in life. And they’re a great couple and I really do hope the best for them."

After Tarek revealed the sex of her baby, Christina's representative confirmed the news. "While Christina and Ant wished they could have shared the news themselves, they are very excited to welcome a baby boy in the fall," the rep said. It's unknown if Christina will confront her ex-husband for sharing the information.

Tarek and Christina filed for divorce in 2017 citing irreconcilable differences after eight years of marriage. Their divorce was finalized in 2018. They share two children together, 8-year-old daughter Taylor Reese and 3-year-old son Brayden James.

Christina went on dating Ant in November 2017 and got married in 2018. In March, they announced that they're expecting their first child together. "@ant_anstead and I are so excited to announce #babyanstead coming this September!! The kids are all so excited to meet their new sibling #5," she wrote on Instagram along with a photo of her sharing an embrace with her husband while she's holding out an ultrasound photo.

Ant also has two kids from a previous marriage to ex-wife Louise, 15-year-old daughter Amelie and 12-year-old son Archie.
