Justin Timberlake's romance with Jessica Biel is getting so serious the actress flew into the U.K. to see the pop superstar on his European tour. The couple were spotted out in Manchester, England, on Saturday (12May07) holding hands and sharing intimate kisses while on a dinner date at high street restaurant chain Nandos. They were joined by super-producer Timbaland and Manchester United soccer star Alan Smith. Timberlake was first linked to The Illusionist actress at the Golden Globes in January (07) - less than a month after he announced his split from girlfriend-of-four-years Cameron Diaz. A source tells British newspaper The Mirror, "Justin's really into Jess and when he found out she had some free time he asked her to join him on the U.K. leg of his tour. "They're both doing everything they can to keep their relationship low-profile but when they're among friends they can hardly keep their hands off each other."
