EXCLUSIVE: Christina El Moussa No Longer Dating Hockey Pro Nate Thompson

Well, that was fast.

Looks like Christina El Moussa is still single!

After the 33-year-old Flip or Flop star was linked to Anaheim Ducks hockey player Nate Thompson last month, a source tells ET that their short-lived romance is already "over." A rep for El Moussa also told ET on Tuesday she and Thompson are "just friends."

"Nothing dramatic happened -- it was super casual from the start, and they were never an official couple to begin with," our source says. "Bad timing on both their ends never really let it evolve into something serious. They remain friends and there are no bad feelings between them at all."

The source also says that El Moussa and 32-year-old Thompson actually called things off a couple of days before the news they were dating broke, and that Thompson is currently back together with his ex-girlfriend, Pilates instructor Sydney Kaplan -- who interestingly enough, bears a resemblance to El Moussa. Thompson and Kaplan attended an ESPYs after-party together last July.

As for why El Moussa was at an Anaheim Ducks game with her close pal on Sunday -- which she posted about on Instagram -- ET has learned that she bought the tickets months ago for the game. El Moussa is a longtime Ducks fan and has had season tickets for years, and was not there to cheer on Thompson.

Last month, a source close to Thompson told ET that the pair had gone on a couple of dates together. "It's still very new and they're seeing where it goes," the source said.

In March, the mother of two told ET that dating was definitely not a priority for her at this time in her life.

"Honestly a relationship is the farthest thing from my mind right now," she said. "It's not even on my radar."
