MUMBAI: Singer Britney Spears' friends are reportedly worried she is moving too fast with her new boyfriend Sam Asghari.

Spears met Asghari on the set of her music video for her single ‘Slumber Party’ last year.

Though the pair seem happy, Spears' friends are concerned she has been thrown off-balance by having a new guy in her life and is rushing into making the relationship more serious than it needs to be.

"Britney has been thrown off-balance by Sam, the hot new guy in her life. Her friends and family have been trying to warn her that she is moving too fast," a source told hollywoodlife.com.

"Those close to Britney are warning her that Sam may not be the best match for a star of her calibre. They are urging Britney to slow down with Sam, even though Britney is way into him and friends fear she trusts him maybe way more than she should," the source added.
