Justin Timberlake & Jessica Biel Reunite in England

Justin Timberlake and Jessica Biel have taken their romance across the pond -- all the way to jolly ol' England!

In the wee hours of May 15, Timberlake, 26, fresh from his show that night at MEN Arena, settled in to the cozy bar of the posh Lowry Hotel in Manchester for a makeout session with Biel, 25.

"They were kissing and holding hands," an eyewitness tells Us Weekly of the duo, who later retreated to the singer's presidential suite.

The pair, who have had a flirtation ever since he split from Cameron Diaz in December, were just as cozy during a private dinner at the hotel three days earlier. "They held hands," says a witness.

Still, sources say neither wants to get serious.

"Jessica has said there is nothing romantic," a Biel source tells Us.

Reps for both stars declined to comment.

Are they exclusive? What are Justin's pals saying about the romance? What's up next for the couple?
