VIDEO: Lady Gaga Talks A STAR IS BORN, Celebrity Crushes, and More on Ellen

Lady Gaga recently appeared on Ellen, where she discussed her upcoming role in A Star Is Born.

The Grammy winning star talked with Ellen about why she can't let go of her character Ally in the film and how her co-star and director Bradley Cooper made the film set a "sanctuary" filled with trust.

Ellen then put Lady Gaga in the hot seat, where she spilled the beans about the most recent lie she told, her surprising celebrity crush, and her reality TV guilty pleasure.

In this new take on the tragic love story, Bradley Cooper plays seasoned musician Jackson Maine, who discovers-and falls in love with-struggling artist Ally (Gaga). She has just about given up on her dream to make it big as a singer... until Jack coaxes her into the spotlight. But even as Ally's career takes off, the personal side of their relationship is breaking down, as Jack fights an ongoing battle with his own internal demons.

The cast of "A Star is Born" also includes Andrew Dice Clay, with Dave Chappelle and Sam Elliott.

In addition to playing Ally, Gaga, who earned her Oscar nod for the song "Til It Happens to You" from "The Hunting Ground," performs original songs in the film, which she wrote with Cooper and a handful of artists, including Lukas Nelson, Jason Isbell and Mark Ronson. All the music is original and was recorded live.

"A Star is Born" is produced by Bill Gerber, Jon Peters, Bradley Cooper, Todd Phillips and Lynette Howell Taylor. Ravi Mehta, Basil Iwanyk, Niija Kuykendall, Sue Kroll, Michael Rapino and Heather Parry serve as executive producers. The screenplay is by Eric Roth and Bradley Cooper & Will Fetters.

Collaborating with Cooper behind the scenes are Oscar-nominated director of photography Matthew Libatique ("BLACK SWAN"), production designer Karen Murphy, three-time Oscar-nominated editor Jay Cassidy ("American Hustle," "Silver Linings Playbook," "Into the Wild"), and costume designer Erin Benach.
