Britney Spears spent $30,000 of her own money on her new music video.

Sources claim the 25-year-old singer funded the promo for comeback single 'Get Back' because she was going against the wishes and advice of her label, Jive Records.

The video, which was shot in a Los Angeles warehouse, features Britney pole dancing in a tiny black dress and thigh high boots.

The extras dancing in the video worked for free but Britney had to pay for the rest of the production costs.

A source told E! Online: "There's no real reason for her to pay for a video herself unless it's about creative control."

"If the label pays for the video, they hire the director and the rest of the creative team."

"I suspect this is her wanting to steam ahead and answer her critics now, while her label wants to wait."

Meanwhile, Britney had to rush her new puppy, London, to the vet on Friday. The mother-of-two looked visibly upset as she drove from her home to the nearby Beverly Hills Small Animal Hospital with the Yorkshire Terrier.

Britney was accompanied by her cousin Alli Sims and sons Sean Preston and Jayden James.

London was seen by a veterinarian and left the hospital 30 minutes later.

Sims said: "It was just a check-up. She is OK."
