'Franklin & Bash': Jane Seymour Returns As Bash's Mom With A Disturbing Surprise (EXCLUSIVE VIDEO)

Jane Seymour returns to "Franklin & Bash" this week (Wed., June 26 at 9 p.m. ET on TNT) to play Colleen Bash, Peter's (Mark-Paul Gosselaar) fun-loving mom. And this time around, she's having a little too much fun for Peter's liking.

In the upcoming episode, titled "Good Lovin'," Colleen is arrested on prostitution charges and in The Huffington Post's exclusive clip above, she attempts to explain to Peter and Jared Franklin (Breckin Meyer) that her methods as a "sex surrogate" are purely therapeutic.

"Well, I don't have sex with most of my clients," Colleen explains.

"She said 'most,'" a disgusted and shocked Peter replies. And it only gets worse for him from there.

Seymour opened up about her hilarious return to "Franklin & Bash" to The Hollywood Reporter recently. "Peter does not do well with that knowledge, and of course they banter among one another and tease him really badly about it. Ultimately, I find out Rachel [Lockear, who plays the new boss] hasn't had sex for six years, and so I kiss her," Seymour told THR. "I really can't tell you much more about the episode without spoiling it. I haven't seen it, but they tell me it's one of the funniest ones they've ever done. It certainly is a really fun role, and I, basically as a sex surrogate, point out to my counsel -- who are my son and his partner -- that I don't have sex with all my partners. That makes it even worse, as you can imagine."

"Franklin & Bash" airs Wednesdays at 9 p.m. ET on TNT.
