Adele said she felt like Beyonce as she hit the red carpet ahead of the Oscars where she is due to perform and expected to take home a statuette.
The Someone Like You star posed for photographers outside the Dolby Theatre in Los Angeles along with stars of the big screen.

The actor is nominated for best actor for his performance in US historical drama Lincoln - his fifth nomination in the category which he has already won twice - in 1989 for My Left Foot and in 2007 for There Will be Blood.

That will take him past the achievements of two-time winning Hollywood legends including Jack Nicholson and Dustin Hoffman - who are both scheduled to present awards on the night.
