Tarek El Moussa and fiancée Heather Rae Young had a nice surprise for his kids at the beginning of the weekend.

As the daughter of the flip or flop star Taylor, 10, and son Brayden, 5, entered the couple’s house, a little black puppy shot out to greet them. Tarek posted videos of the children’s reactions on his Instagram story.

“Surprise!” What’s this?! What is that ?! “he exclaimed, pointing to the bitch, who looked like a pug, as she ran across the floor.

Tarek has given the clip a title: “We have expanded the El Moussa family! Meet Bugz El Moussa. ”The kids looked delighted and Taylor hugged the puppy enthusiastically while Brayden gently patted her head and received lots of dog kisses in return.

“I hid them from you and from them for a week,” he wrote, “but the reaction was worth it.”

Earlier this week, Tarek wrote on his Instagram page that “the kids are gone for a week and we’ll miss them like crazy,” adding, “We have a big surprise planned for them on Friday.”
