Melanie, 55, who portrays Sabrina's (Shannon Woodward) self-absorbed mother Tamra, told The Insider her character is definitely a cougar ready for some action. "He's very sweet and he's really very polite and wonderful with me... he's playing it really smooth," she said. Melanie's real-life mother Tippi Hedren, 82, has also guest-starred this season playing her character's mom on the show.

She also teased that she does indeed share some kissing scenes with 32-year-old Wilmer, who for his part said that getting to work with Melanie was a dream come true. "I never thought that Melanie Griffith and I would ever be love interests in my career. So this is definitely a treat and a very exciting one," he said.

Wilmer also confirmed that the two have some intimate scenes, which he described as "very passionate," but he said they couldn't be too steamy and still make it on primetime TV.
