Chrishell Stause and G Flip have taken their relationship to the next level: Showtime.

As the couple played themselves in a cameo on this weekend's season 3 finale of The L Word: Generation Q, they celebrated the episode at a watch party Sunday night with cast, fans and fellow special guest star, pop breakout Fletcher.

"Thank you @sho_thelword @showtime for letting us play! Gigi for next season of #SellingSunset," Stause, 41, joked in the caption of a realtor character (portrayed by Sepideh Moafi), whom she mentions in the scene.

She and G Flip, 28, posed for photos at the event with Fletcher, 28, as well as season 3 star and scene partner Paula Andrea Placido.

G Flip, who is non-binary and uses they/them pronouns, also shared a video from the watch party of the couple and the crowd reacting to their scene. "Babies on TV," they wrote with the clip.

In one behind-the-scenes throwback photo, the couple sat outside their adjoining trailer. They posed with star Jacqueline Toboni in another.

"We were both with our ex-partners then ... And then, we obviously separated from our partners, and we just started talking and stuff," G Flip continued. "We just found a lot of similarities, even though people would think we are from like different corners of the world. We find ourselves so similar sometimes."
