Tarek El Moussa may be involved in a nasty divorce with his estranged wife, Christina — but that didn’t stop him from celebrating Valentine’s Day!

The star of Flip or Flop took to Instagram to write a sweet post to the leading lady in his life — his daughter, Taylor (with a sweet shoutout to her one-year-old brother, Brayden)!

The reality star, 35, shared a precious pic with his six-year-old daughter and wrote, “Happy Valentine’s Day to the love of my life! Our bond is stronger than ever and I’m so lucky to have this angel in my life. She is my absolute best friend and my heart and soul… I can’t wait to be by her side and watch her grow for the rest of my life. She is so amazing that words can’t describe it. Daddy loves you Tay! And of course, the world’s most amazing boy, Brayden!”

The touching message was posted shortly before In Touch exclusively revealed that Tarek hired a private investigator to follow his wife while they were still married because he was suspicious she was seeing another man (her now-boyfriend, Gary Anderson).

“When he and Christina were on the rocks, he confessed to the production crew that he suspected she was dating someone, so he hired a private investigator to follow her. He wanted to know where she was going and what she was doing,” a source tells In Touch exclusively. “It’s hard for Tarek to see Christina dating, but it’s even worse that Gary is the guy she’s with.”
