The single life certainly looks good on Christina El Moussa!

The Flip or Flop star showed off her stunning hair makeover on Sunday while speaking at the 2017 Real Estate Wealth Expo in Chicago — and we must say, hot damn.

Christina showed off a curlier 'do for the occasion, a far cry from her signature straight look. Between this and her bikini body, Tarek El Moussa can eat his heart out!

The mother-of-two also spoke about her early days with Tarek, though it was revealed in December they were separated and he filed for divorce in January.

"We had no money. Tarek told me we were going to get a TV show. He made me follow him around with a little video camera that we borrowed. And we did all the work ourselves," she explained.

As for her ex, the fellow HGTV host teased he is going through a mid-life crisis after revealing his sexy new photoshoot and new hairstyle — because two can play this game, Christina!

"OH NO! New #clothing. New #hairstyle. #No more sandals! Half #naked pics! Is this a mid-life crisis?" he teased on Instagram. "My sister hooked up the new #hollyweird hair style @l33hairartistry — looking pretty fly for an #old guy!"

Christina moved on from their split at first with contractor Gary Anderson and was recently rumored to be dating NHL star Nate Thompson — though her rep insisted they are just friends. Tarek moved on with their young nanny, Alyssa Logan — though they are no longer together.

He recently divulged what triggered him to file for divorce.

"I feel like if we had better communication, we would have had a better relationship. I think as time went on, you get busier and busier. It was like overnight: businesses, TV, all these things happened overnight, then the cancer and the back surgery. It just kind of started pushing us apart from each other," he explained during an appearance on The Doctors.
