Former Jenny Craig spokesperson Kirstie Alley bravely appeared on "The Oprah Winfrey Show" today to address her weight gain and react to images of Valerie Bertinelli in a bikini. Now, we're showing the footage to Valerie, who is incredibly amused at Kirstie's outrageous reaction!

"I miss you Kirstie, come back to me!" Valerie says, with our Thea Andrews looking on. "I love her. She's so real!"

Asked if she thinks Kirstie's a little jealous of her brand-new bikini bod, the current Jenny Craig spokesperson replies, "Not Kirstie. No. I think if anything, she is probably proud of me, and she is probably proud of what she helped me accomplish. I don't think she's jealous at all. I think she's proud of her work."

Valerie says she actually joined Jenny Craig because of Kirstie: "She was the greatest mentor, is the greatest mentor. She is such an inspiration."

The former "One Day at a Time" star says Kirstie sent her flowers when she did her first "skinny jeans" Jenny Craig commercial without her, and she'd welcome the opportunity to make more commercials together.

"If I could say anything to Kirstie -- and I want to talk to her so badly -- come back so we could do this again!" she says.

Valerie adds that Kirstie, or anyone for that matter, did not let anyone down because she gained weight back. "It's not a failure to stop something and go, 'Hmmm, you know what, it's not working for me being off it. I think I'll get back on,'" she says. "I saw that sparkle in her eye. I don't think she's done yet."
