After only three months together, Flip or Flop star Christina El Moussa and her boyfriend, British television host Ant Anstead, are so serious, they're talking about walking down the aisle together.

"They would love to get married, and they’re discussing it already," an insider tells Life & Style. "Christina knows Ant is 'the one,' and the feeling is mutual."

There's a pretty serious obstacle, though: While Christina, 34, recently finalized her divorce from Tarek — her HGTV co-host and father of her two kids — Ant, 38, is still married to his wife, Louise.

The duo, who also have two children, separated in July, though, and the good news is the divorce shouldn’t be too complicated. "Ant and Louise were childhood sweethearts, and they remain on good terms," the insider tells Life & Style. "It's unlikely that their divorce will be long and messy."

Tarek won't be raising any objections to Christina's new romance either. "Tarek has given them his seal of approval," the insider says. "He's pleased she's found happiness with an age-appropriate, decent guy."
