Another way to bond! Kim Zolciak and her daughter Brielle Biermann opened up about getting lip injections during Watch What Happens Live on Wednesday, September 14.

The Don't Be Tardy matriarch, 38, discussed getting plumper lips when a viewer asked why she allows Biermann, 19, to get injections done.

"First of all, she's almost 20, so talk to her. And then, why not? Shoot it up!" the Real Housewives of Atlanta alum said.

"I've heard her complain about her lips since she came out of the womb, honestly. And she said, 'I'm doing it,'" said Zolciak, then added, "I was like, 'I'm going to take you to the best.'"

Biermann, who joined her mom on WWHL, documented getting lip filler injections via Snapchat in July. The pair now make it one of their priorities when they travel to L.A.

"You're never done — it disintegrates," Zolciak told host Andy Cohen. "I didn't do it with her — I already had mine done."

Biermann chimed in: "It only lasts, like, three months or something like that, so when we go out to L.A. every three or four months …"

Back in May, Zolciak again defended Biermann's lip injections. "She bothered me for five years about her lips. She was like, ‘I hate my lips, I hate my lips.’ So I’m like, then go fix them! You only go around this planet once. If it makes her happy, so be it," she exclusively told Us Weekly at the time. "She is a leader, not a follower. Social media sucks. It’s been difficult. I try to monitor my girls’ accounts, but Brielle is 19. But she can handle it better. She has confidence."
