Justin Timberlake turned a business trip to Switzerland into a romantic birthday vacation for his girlfriend Jessica Biel. The pop star flew to Europe last week to attend the Geneva Auto Show and launch the new Audi car as part of his role as a brand ambassador for the motor manufacturer. And Biel flew out to join him to celebrate her 28th birthday on Wednesday (March 03). The couple was pictured walking through the city arm-in-arm and enjoying a sledding trip in the nearby town of Verbier.

Jessica Biel revealed that the most romantic moment of her life was when her other half left a trail of rose petals for her to follow. “The most romantic thing someone has ever done is given me flowers — but they left a trail of petals all along the floor leading all the way through the house to other surprises,” she said. “It was so lovely. And a surprise.”

Jennifer Garner has been giving relationship advice to her Valentine’s Day costar Jessica Biel. Insiders say Garner — who’s married to and raises two children with actor Ben Affleck — gave Biel tips on how to kickstart her romance with on/off boyfriend Justin Timberlake. “She even came up with a ‘relationship cheat sheet’, including ways Jessica could spice things up and play hard to get at the same time,” a source said. “Jen told Jess to calm things down, and remind Justin what attracted her to him in the first place.”

Jessica Biel isn’t sure if she believes in love at first sight. The actress believes one has to get to know a person before they fall for them. “I don’t know if I believe in love at first sight,” said the Valentine’s Day star. “I think often you can meet somebody and you don’t realize it, until later and then you go ‘Oh my God, I think that love happened, I just wasn’t sure that it happened.”

Jessica Biel was on a sugar high for days while filming new movie Valentine’s Day after she was forced to repeatedly munch on doughnuts and chocolates in one indulgent shoot. The actress is part of a star-studded cast in the new Garry Marshall romantic comedy, which includes Julia Roberts, Jennifer Garner, Jessica Alba, Ashton Kutcher and Bradley Cooper. And one particular day of filming left Biel buzzing around on set. She says, “We shot both scenes on the same day. So in the morning I ate about 10 doughnuts; in the afternoon I ate about 18 or 20 chocolates. I was on a sugar high for days, it was crazy!”

Pretty Woman director Garry Marshall is taking Jamie Foxx’s advice and pushing forward with a movie remake of his hit TV sitcom Laverne & Shirley with new best pals Jessica Biel and Jennifer Garner in the title roles. The actresses became bosom buddies on the set of Marshall’s new film Valentine’s Day, prompting their co-star to suggest they’d be perfect for a Laverne & Shirley remake. And Marshall admits he’s committed to making the movie, which will feature cameos from his sister Penny and Cindy Williams – the original Laverne & Shirley. He says, “We’re gonna work on that. My sister Penny and Cindy are going to be a guest cameo (sic).” And Garner can’t wait to work with her new best friend: “Are you kidding? We’re dying to do it.”

Jessica Biel has a “girl crush” on Julia Roberts. The actress – who is dating Justin Timberlake – admits she and the ‘Pretty Woman’ star bonded instantly on the set of their new movie Valentine’s Day and can’t bear to be out of contact with one another. She said: “I hear she has a girl crush on me and I definitely have one on her. I think she is amazing. Although I did panic for a while because I sent her a text and she didn’t reply for a while. But we’re fine now.” The 27-year-old star – whose romance with Justin has been the subject of much speculation that it is on the rocks – also claimed to have no plans to celebrate Valentine’s Day (February 14) with the singer because she is too busy with work. However, she added: “I love Valentine’s Day! It’s great to take a day out and celebrate loving and caring for people… It’s great!” As well as her feelings for Julia, Jessica has previously admitted to having a crush on another of her female Valentine’s Day co-stars. Speaking about Jennifer Garner, she said recently: “My girl crush is Jen at the moment but here’s the thing with girl crushes – it’s more of a respect thing. It’s like, you’re beautiful, you’re cool, you look and seem like somebody I would want to hang out with and your career is awesome.”

Jessica Biel will not climb Mount Kilimanjaro again. The Valentine’s Day actress was glad she scaled Africa’s highest peak, but the physical challenge left her “miserable”. She said: “I’m never going to that again. I just got back six days ago. It was incredible. “It was such a challenge for me. It was probably one of the hardest things I’ve ever done… sometimes it was kind of miserable. “Altitude sickness is like a general uncomfortable, uneasy feeling. You just can’t think straight.” However, the 27-year-old actress has suggested everyone should undertake a huge challenge like the one she completed at least once. She added to Access Hollywood: “Hiking for seven hours a day and sleeping in tents and being out in the wilderness was a real experience everyone should try.” Jessica undertook the trek up the mountain to raise global awareness of the world’s water crisis alongside actor Emile Hirsch and other philanthropists including Kick Kennedy – granddaughter of Robert F. Kennedy and executive of the UN Foundation Elizabeth Gore.
