The actress is taking inspiration from her new show's network, Bravo.

Legally Blonde star Alanna Ubach is ready for a Delta Nu reunion!

Reese Witherspoon totally has our hopes up for Legally Blonde 3. Back in October, the actress told ET she was speaking with the screenwriters, Karen McCullah and Kirsten "Kiwi" Smith, about the project.

So, when ETonline caught up with Witherspoon’s co-star on set of her Bravo show, Girlfriends’ Guide to Divorce, we had to know where Ubach thinks Serena -- her character in the first two flicks -- would be in the three-quel.

“She would probably be... I'm assuming one of those Housewives of Beverly Hills, or something like that,” Ubach guessed. “Maybe the next Bethenny Frankel, I'm assuming. Who knows? Who knows? That's what the writers are for. Karen, Kiwi, get cookin'!”

Ubach’s answer was perfect because there was an actual Real Housewife on the Girlfriends’ Guide set that day: Orange County star Shannon Beador! The reality star dropped by to film a cameo for season two.

“Well, I'm playing myself,” Beador told ETonline before her scene. “So I'm not really acting, 'cause I'm not an actor and I don't think I ever will be one … The ratings are gonna shoot up after I'm on this show... just kidding!”

Girlfriends’ Guide’s new season does look juicy. Here’s what the cast told ETonline on-set:

“More nudity,” Necar Zadegan, who plays Delia, teased. “More drama, more sex, more debauchery, more bad decision-making. Just general T-R-O-U-B-L-E. It's gonna be good.”

"I think this year is funnier and more raw,” star Lisa Edelstein (Abby) said. “It goes deeper, for everybody. It's a pretty intense storyline."

“Jake and Abby are giving it a go,” Edelstein’s on-screen ex, Paul Adelstein, explained. “So, you know, it's gonna be Jake and Abby 2.0, seeing if they can keep it together without falling back into their old patterns.”

“It’s a really cool season,” Ubach promised.

Girlfriends’ Guide to Divorce’s second season premieres Tuesday, Dec. 1 at 10 p.m. ET on Bravo.
