Hilary Duff and Ashton Kutcher are to bring romance back to the set of "Two and a Half Men."

Duff is the guest star on the season finale of the show playing Kutcher's love interest, episode airing May 9 will have a unique twist that will also include Marilu Henner.

E! News confirms Duff to portray Stacey, as the love interest of Walden (Ashton Kutcher). Henner is to play Duff's grandmother on the CBS comedy's season finale.

The former "Lizzie McGuire" star described her character on Twitter.

Duff however will not be alone fighting for Kutcher's attention. TVLine spoiler alert explains that Kutcher's character will fall in love with Duff's grandmother to complicate the story.

CBS has yet to officially renew the show for next season, therefore no surprise that there are rumors that this may be the series finale.

The pair has been together on screen before as they both starred in 2003 movie "Cheaper by the Dozen." This isn't a first portraying lover of vastly different ages, as Miley Cyrus was on the show, flirting with Kutcher however ended up dating the youngest member of the show, Angus T. Jones.
