Lisa Rinna's 18-year-old daughter, Delilah Belle Hamlin, has joined a dating app and her mother doesn't seem to thrilled. In a sneak peek at tonight's new episode of "The Real Housewives of Beverly Hills," Rinna and her co-star, Kyle Richards, take their daughters, including Delilah and Amelia Hamlin and Sofia Umansky, out for a meal and as they sit and chat, Delilah points out a recent "match."

"Okay so there's this dating app... Just listen," Delilah tells her mother in a sneak peek shared by Bravo TV. But all Rinna wants to know is whether or not her model daughter is signed up.

"You just talk to them," Delilah explains. "You don't go meet them, do you?" Rinna wonders.

According to Delilah, she doesn't meet up with the people she's matched with and the app is more than just a dating app. As she proceeds to explain, you can also form business relationships on the app and only "really special" people can be a part of it.

"You are scaring the s**t out of your mother right now," says Richards.
