Christina Hall, Heather Rae Young and Tarek El Moussa are clearing the air! The reality tv stars took to Instagram Thursday to share pics of their united family as they attended an event for their 11-year-old daughter, Taylor. "Co-parenting 101. Kids come first," Christina wrote. Tarek posted a pic from the same event, and Heather shared the same snap. "Sometimes to shut down the noise we show the truth," Heather wrote. Their posts come amid a rumored spat among the stars earlier this week.
