Oscars 2015: Stars Getting Ready for the Show

Feb. 22, 2015— -- The stars were making last-minute preparations ahead of Hollywood's biggest night.

Rita Ora, who is scheduled to perform the Oscar-nominated song "Grateful" from the movie "Beyond the Lights," posted a picture of herself doing a bit of pampering beforehand.

"Pre Oscar pampering booooooom," she wrote on Instagram.

Fellow performers John Legend and Common, who are nominated for their song "Glory" from the film “Selma,” got in a little rehearsal time before the big show.

"Post rehearsal, pre Oscars photo w/ @common," Legend wrote alongside a photo of the pair in what looks like an elevator.

Common started his day going to church.

Another performer, Tim McGraw, who is stepping in for Glen Campbell to sing his Oscar-nominated "I'm Not Gonna Miss You," shared a snap from backstage.

"Do y'all have any #Oscars watching traditions?" he asked his Instagram followers.

McGraw also posted a photo of himself getting a pre-Oscar manicure. "The things you do for the #Oscars...," he wrote

Marion Cotillard, nominated for best actress for "Two Days, One Night," had a bit of fun with her prep team.

Reese Witherspoon enjoyed flowers from hubby Jim Toth on Oscar day.

"The best thing to have on the red carpet is someone who loves you and supports you....(and buys you flowers.) I (heart) my #Oscars date!" she wrote alongside a photo of the white roses.

Oprah Winfrey also shared a backstage shot from rehearsal the day before.

Channing Tatum also posted a selfie from his rehearsal Saturday.

Gaga, who has a special performance planned tonight, was clearly having fun at the rehearsal Saturday.

"Lookie NO TOUCHIE #Oscars," she wrote alongside a photo of her.

Meanwhile, the evening's host, Neil Patrick Harris, got a little visit from a previous Oscar host. You have to wonder what advice Hugh Jackman had for him.
