Jessica Biel has joined Justin Timberlake on his European tour again. Jessica, who recently visited Justin while he was performing in the UK, arrived in Amsterdam on Sunday, where the couple stayed at romantic five-star hotel The Dylan. Justin and Jessica travelled to Sweden the following day and were seen dining at Stockholm's Lebanese restaurant Beirut Café with 13 members of the singer's entourage. Restaurant owner Elias Karroum told People magazine: "They seemed like an ordinary couple in love. They were very sweet."They also tried to smoke a water pipe with apple-flavoured tobacco. They said they'd tried it before, but we had to show them how to do it properly."The couple were first romantically linked earlier this year, just weeks after Justin, 26, split from Cameron Diaz. Last week, the 'SexyBack' singer admitted it was a bad idea for Jessica, 25, to join him on the UK leg of his tour. Justin said: "She truly insisted that she came with me on tour. I don't know how to say no to a pretty face. But it wasn't really a good idea. Jessica met up with me in Manchester, but for Paris I told her categorically no."This tour is very important for me. I'm doing it really seriously so there's no question of playing sweethearts."
