Pamela Anderson and Tommy Lee have sparked rumours of a reunion after they were spotted together in Las Vegas.

The pair, who divorced in 1998 following three years of marriage, were seen drinking at the Body English club inside the Hard Rock Hotel.

Photographs also show Anderson eating sweets from a necklace around Lee's neck at the private party, which followed Motley Crue's gig in the city.

“They were making out all night and biting each other's candy necklaces,” a source told The Sun newspaper.

"Later, they headed to Vince Neil's Paradise Tower mega suite to continue partying."

Anderson and Lee's whirlwind marriage infamously generated a honeymoon sex tape, which became a worldwide hit.

The former couple also had two children together: Brandon Thomas Lee and Dylan Jagger Lee.
