A new man is not the only thing new in Britney Spears' life these days.

Spears debuted a new shade of brunette hair at Elton John's Oscars bash on Sunday evening in Los Angeles.

The 31-year-old singer's signature platinum locks have been dyed a soft, chocolate brown, which is a shade closer to her natural color.

Spears also dared to bare plenty of cleavage in a sparkling black Michael Cinco Couture dress with cap sleeves and a sheer back, according to Just Jared.

On Sunday, the former "X Factor" judge partied alongside the likes of Kim Kardashian , Miley Cyrus, Heidi Klum and Emma Roberts, ABC News notes.

Its a great mix of people, John told ABC.

Noticeably absent was Spears' rumored new boyfriend , David Lucado.

The superstar was first spotted out with the 27-year-old Atlanta native on Valentine's Day, TMZ reported. A few days later, Spears and Lucado were seen playing golf at the Sherwood Country Club, near where Spears lives. He is said to be the "exact opposite of a Hollywood guy."

The last time Spears went brunette was back in 2009 , when she began dating Jason Trawick.
