Justin Timberlake and Jessica Biel's romance heats up

Justin Timberlake's rebound relationship with Jessica Biel seems to be going quite well. The pair, who were first linked in January, have been spending time together in the British city of Manchester.

Says a source for the Mirror's 3AM Girls, "Justin's really into Jess and when he found out she had some free time he asked her to join him on the UK 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."

The loved up couple have been enjoying Justin's nearly $4,000/night suite at the Lowry Hotel. A witness to one of Jessica and Justin's PDA sessions in the swank hotel told the Sun, "There was lots of touching and kissing."

But Biel and Timberlake are relatively low-key and eschewed more luxurious outings for a cheap meal on Saturday. Joining them for the $20/person at Nando's was Timberlake's producer Timbaland and Manchester United soccer player, Alan Smith. The next day, Jess and Justin watched Alan's team lose to West Ham United. Said 3AM's insider, "Justin's not into pretentious, posh food and as he loves sport he jumped at the opportunity to catch a United game with his woman."
