OTRC: Kelly Osbourne, Miley Cyrus in sorority movie together

Kelly Osbourne says she's honored to present Pink's performance at the 2010 American Music Awards.

Kelly Osbourne and Miley Cyrus, who recently made headlines for a video that shows her smoking out of a bong, are filming a sorority comedy movie called "So Undercover" and are said to have gone clubbing recently in New Orleans.

Osbourne, a 26-year-old reality star and daughter of heavy metal rocker Ozzy, and Cyrus, the 18-year-old star of the Disney Channel show "Hannah Montana", have not commented on the "girl's night", reported by People magazine.

"So Undercover" is set for release in 2011 and tells of a private detective who is hired by the FBI to go undercover in a college sorority. It is Osbourne's second movie. The former "Osbournes" star and "Dancing With the Stars" contestant recently filmed the comedy "Should've Been Romeo," which marked her big screen debut and is also due to hit theaters in 2011.

"Today is my first day of filming," Osbourne said on her Twitter page early on Tuesday, adding that she woke up at 4 a.m. "I'm so excited for my first scene."

She said on Friday that she was in New Orleans to film a movie with Cyrus and added the two were "having a blast". Osbourne said on Sunday that she spent the weekend bonding with her cast mates.

Osbourne and Cyrus were spotted at the New Orleans club Republic at 1:30 a.m. on Saturday actress Alexis Knapp and two other women, People said, quoted a source close to the matter as saying:"It was a good, old-fashioned girl's night. They were just dancing and hanging out. Miley was drinking Red Bulls."

Cyrus has not commented on a recent video posted on TMZ that showed her smoking out of a bong, swearing and laughing uncontrollably.

Cyrus' spokesperson denied comment. TMZ , which posted the footage late on Thursday, said she was smoking the natural herb salvia, which is legal in California and has hallucinogenic effects.

Cyrus' father Billy Ray, a rock singer who is also her costar on "Hannah Montana", said on his Twitter page on Friday afternoon, half a day after the TMZ video was posted: "Sorry guys. I had no idea. Just saw this stuff for the first time myself. Im so sad. There is much beyond my control right now."

Cyrus rose to fame with "Hannah Montana," which is set to end after the current fourth season.

She has said she has outgrown the series and also caused some controversy earlier this year when she showcased a more mature image in performances and music videos, which marked a sharp contrast to her "good-girl" persona seen on the show. The actress and singer says she has changed since she began filming "Hannah Montana".

Cyrus, who began her acting career when she was eight, also stars in the 2011 film "LOL: Laughing Out Loud" with Demi Moore and plays a girl who deals with high school romances and friendships as well as overbearing parents.
