Tarek, 35, and Christina, 33, attended the 44th Daytime Emmy Awards together on Sunday, April 30, following their split, Us Weekly reported.
The exes were reportedly all smiles on the red carpet at the Pasadena Convention Center in California, walking and posing together for photos arm-in-arm. The couple presented the award for Outstanding Entertainment News Program dressed in matching black ensembles.
Tarek and Christina appeared happy and friendly shortly after HGTV announcedFlip or Flop will be airing an extended, 20-episode seventh season beginning in December 2017. The couple continued to film episodes of their home-renovation show although their seven-year marriage had fallen apart and ended.
"Tarek and I have been working together for a long time and we look forward to continuing to work together on Flip or Flop," Christina said in a statement last week.
"From the beginning, HGTV has shown Christina and me tremendous support and we are excited to go out there and flip many more houses for Flip or Flop," added Tarek.
Tarek and Christina split in Spring 2016 following an altercation in their Orange County, CA, home, and admittedly began dating other people, although not seriously.
Around that same time, Tarek told Us Weekly that the pair will be "together for the rest of our lives" because they are parents to daughter Taylor, 6, and son Brayden, 20 months.
"We need to get along for the kids and for our sanity," Tarek said. "There haven't been fights. We have fifty-fifty custody now. She's a great mom and I like to think I'm a great dad. Sometimes she or I will say, 'I need them for an extra day or two.' We're both flexible."
After calling it quits on their romance, Tarek and Christina seemingly got into the best physical shape of their lives via diet and exercise. Christina has been sharing gorgeous modeling photos as well as bikini pictures online, while her estranged spouse shared his personal fitness story on Instagram.
