Hilary Duff guest stars in the upcoming season finale of Two and a Half Men, where she plays a woman trying to seduce Walden, played by Ashton Kutcher.

According to Entertainment Weekly, Duff's character is named Stacey, who Kutcher actually uses to get closer to her attractive grandmother, played by Marilu Henner.

Duff posted a photo on Twitter of herself in character last month, writing, "Oh Stacey #Partygirl where's my #solocup ooh #tags..."

25-year-old Duff told omg! Yahoo, "I didn't do any kissing! My character was trying to real hard, though, and she kept getting declined!"

Duff had worked with Kutcher before on Cheaper by the Dozen back in 2003, and says she was excited to work with him again. Although he tends to show off his funny side, Duff says he's actually "a really deep guy."

Duff most appreciated working on the show because of her filming schedule, which allowed her time with her family. She said, "I would get to go be with my son at the park and be finished by three o'clock in the afternoon."

The season finale of Two and a Half Men premieres on May 9.
