Tarek El Moussa and Heather Rae Young looked like they had worked up a sweat as they left a hot yoga studio in Newport Beach, California.

The HGTV Flip or Flop star, 39, and the 33-year-old model were flushed and perspiring after their workout on Friday.

Tarik's brunette hair was slick with sweat as he and his stunning fiancee strolled through the parking lot to their car.

El Moussa was also perspiring through the gray t-shirt that he was wearing along with black athletic shorts and black flip flops.

He was carrying a bottle of water and a black baseball cap as he and Heather tried to cool down after their intense exercise class.

The Selling Sunset star was clad in a black sports bra that showcased her taut midriff and toned arms. She paired the sports bra with cropped beige velour sweatpants.

Young was also sporting a pair of fuzzy leopard-print slippers and carrying a beige jacket. The blonde beauty's tresses were pulled back into a top-knot.

The Playboy Playmate's face was extremely flushed following the workout. The couple are avid fans of hot yoga, as Tarek credits the exercise with helping him cope with his divorce from Flip or Flop co-star Christina Haack in 2018.

In an October 2020 interview with Hello! magazine. Heather said, "Since four months ago, Tarek and I have been going to hot yoga two to three times a week and I don't just go to look good, or to stay fit, I also go for my mind.'

'And it's been such a great bonding experience to do it together, and I look forward to it. And when we leave, I just feel like my mind is clear and just happier. I am obsessed with it.'

Tarek shares two sons, Taylor, 10, and Brayden, five, with Christina. He and Heather began dating in July 2019 and got engaged on their one-year anniversary. They are planning to tie the knot over the summer or late fall but have yet to release specific details about their nuptials.

However, the bombshell recently sparked speculation that the two had already secretly wed after referring to Tarek as her husband in her Instagram stories.

On Thursday night, she shared a video to Instagram Stories that was taken in the backseat of a chauffeured SUV. Young addressed her viewers and explained that she and Tarek were on their way to an event hosted by their friends.

'I am freezing cold, my husband is freezing me out in the car so we always keep blankets to be nice and cozy,' Heather said, while pulling a fluffy gray blanket over the front of her strapless red dress.

'Say hi, baby!' She added, turning the camera to face Tarek, who smiled and waved.
