Taylor Swift for Girls?

Taylor Swift is reportedly set to star in Girls.

The American songstress is said to be a big fan of the Golden Globe winning show, and is also good friends with the creator and star of Girls, Lena Dunham.

Now sources close to the famous pair say that a guest appearance is in the pipeline, with Lena apparently eager to make the role a more substantial one.

"Lena's been trying to persuade Taylor to appear in Girls for ages. Taylor loves the show and has agreed a cameo. Lena would also love her to take on a more permanent role and to pen some music for the show," an insider revealed to British magazine Grazia.

Girls star Allison Williams, who plays uptight Marnie Michaels, often showcases her singing voice on the show, so any new music wouldn't feel out of place.

Taylor isn't the first star to be approached to appear in Girls. Irish funnyman Chris O'Dowd took on the recurring role of as Thomas-John, while J. Crew creative director Jenna Lyons moonlighted as Lena's character Hannah Horvath's boss in season three.

The show insider also divulged that model-of-the-moment Cara Delevingne may also be up for a part.

"Taylor told Lena that Cara is a huge fan of Girls. Lena immediately agreed because Cara is her girl crush. She has been in touch with Cara's people already to discuss the idea," the source added.

Earlier this year rumours circulated that Victoria Beckham was set for an appearance on the show, but Lena shot down the gossip by claiming the British fashionista was too chic.

"Victoria Beckham mentioned she loved the show in an interview and this has been metastasised into 'Victoria Beckham is the fifth Girl'. We love Victoria Beckham but she's a little chic for us," Lena previously stated.

Taylor has previously helped out Zooey Deschanel with a small part on hit show New Girl.
