Just as things looked to be getting better for troubled Britney Spears it appears she has reunited with her badboy former lover Adnan Ghalib.

The popstar is taking a break in Las Vegas before before attending the MTV Video Awards later this week. And she has been showing off her newly svelte figure, looking better than ever as she relaxed by the pool in a tiny bikini before heading out in a slim fitting sundress.

But also in the city is Birmingham paparazzi Adnan, who has been accused of having ulterior motives by Britney's father Jamie.

The 36-year-old has barely been seen with Britney since she  was hospitalised for psychiatric treatment in January.

But despite Britney's father's staunch disapproval of Adnan, the pop star is understood to have started seeing Adnan again, TMZ.com reported.

However sources claim the two haven't got back together for purely romantic reasons - Britney is apparently terrified Adnan has an explicit video of her, filmed during the couple's brief trip to Mexico in January.

'Britney's really scared that Adnan has a sex tape,' an insider told MailOnline last month.

'She wants to get it out of his hands.'

Britney's father, who is still her legal custodian following a legal order earlier this year is said to have made his dislike of Adnan obvious.

'Britney's father can't stand Adnan,' said the source.

'He thinks he's seedy, with ulterior motives.'

Britney stunned fans when she started dating Adnan last Christmas after years of complaining about paparazzi attention.

But after her recent troubles, including losing custody of her two young sons, the star seems to be getting her life back together. She has been working out to get back her former figure, and is planning on relaunching her career with a duet with former flame Justin Timberlake.
