Christina was all smiles when she was photographed heading to a romantic dinner with her new boyfriend, Doug, on Friday, June 9, Us Weekly reported.
Christina, 33, and the Orange County businessman were spotted holding hands as they walked to Mastro's Steakhouse in Costa Mesa, CA, for their date.
The blonde beauty was wearing a long-sleeved, purple polka-dot mini dress and gray thigh-high boots, while Doug was sporting a gray button-down shirt with black pants and leather shoes.
Christina also reportedly took to Snapchat to boast about her evening out, captioning a video of a flaming cocktail, "Date night."
Christina and Doug have been dating for about a month now, according to an Us source. Christina recently reconnected with Doug, a man she has known for 10 years whom she dated before ever getting romantically involved with her ex, Tarek El Moussa.
Meanwhile, Tarek has been bragging about how much fun he's having dating multiple women and living the single life as a "free spirit."
It's been about one year since Tarek and Christina quietly split after seven years of marriage and began dating other people.
However, the HGTV reality stars -- who have two children together, Taylor, 6, and Brayden, 20 months -- didn't publicly announce their decision to part ways until December 2016. Tarek officially filed for divorce in January 2017.
Prior to her romance with Doug, Christina appeared to have a brief fling with one of the family's former contractors, Gary Anderson, as well as NHL player Nate Thompson.
Tarek, 35, has been linked to one of the couple's former nannies, Alyssa Logan, as well as several unidentified woman.
Flip or Flop's seventh season will premiere in December 2017 with 20 new episodes, which is more than a traditional full-season order, on HGTV.
