25-Year-old actress Hilary Duff will join the cast of "Two and a Half Men" as Ashton Kutcher's love interest Stacey.

Duff will appear alongside Kutcher on the May 9 season finale of "Two and a Half Men." Hilary Duff will play Stacey the latest in a long line of sweethearts for Kutcher's character Walden. The TV romance between Hilary Duff and Ashton Kutcher will be short lived since his character Walden will fall in love with Stacey's grandmother. The grandmother character will be played by "Taxi" star Marilu Henner.

The "Two and a Half Men" finale will mark Hilary Duff's return to TV since becoming a mom in 2012. Duff is married to NHL player Mike Comrie of the Pittsburgh Penguins. Comrie and Duff were married in 2010; they have a 1-year-old son named Luca.

Duff did an interview back in February with US Weekly. In it the new mom discussed how she dropped all of her pregnancy weight.

"My one trainer helped me lose a sh-t ton of weight. I lost like 30 pounds. His name is Gabe Johns and he is amazing. He's a boxing trainer and he comes to my house. I live in the canyon, so we just run. He runs my ass up and down the hill."

Hilary Duff rose to fame as the star of the Disney Chanel show "Lizzie McGuire." Duff played the title character, a middle school girl just trying to fit in. The success of the TV show spurred a feature film, "The Lizzie McGuire Movie."

Hilary Duff has also starred in other films such as "A Cinderella Story," "Raise Your Voice," and both "Cheaper By The Dozen" films.

Looking to get away from her teen girl image Hilary Duff has been taking on more serious roles in a series of independent movies. Duff was originally cast as Bonnie in an independent film, "The Story of Bonnie and Clyde." Actress Lindsay Pulsipher replaced Hilary Duff when she learned she was pregnant.  

Aside from her movie roles Hilary Duff has released three studio albums and created her own clothing line "Stuff by Hilary Duff."
