Justin Timberlake & Jessica Biel: It’s Serious!

After a rocky stretch, Jessica Biel’s romance with Justin Timberlake is hotter than ever- she’s even won the all-important approval of his beloved mom, Lynn Harless! As Star recently reported, Justin had banished Jess from the European leg of his worldwide Future-Sex/LoveShow tour, telling a British newspaper, “This tour is very important to me. I’m doing it really seriously, and there’s no question of playing sweethearts.��?

But the love-stuck pop star apparently had a major change of heart! On June 17, Jess, 25, flew to Stockholm to be with her beau. That night, the two headed to the city’s chic Berns Hotel, where “they sat and made out and touched each other for everyone to see!��? says an eyewitness. Later, the couple met up with 11 friends for a three-hour meal at the popular Lebanese eatery, Beirut Café. Justin later told a local newspaper, “We had a fantastic evening!��?

The real proof of JT’s affections, however, was yet to come. On June 19, he flew his mom, Lynn Harless, to Stockholm to check out his new flame! How crucial is Lynn’s endorsement of the relationship? Mama’s boy Justin, 26, has her initials tattooed on his back, along with the word “guardian.��? And Jess seemed eager to please the woman who could someday be her mother-in-law, presenting Lynn, 46, with a simple silver charm bracelet from Tiffany & Co. as a welcoming gift!

Later that day, the women seemed like old friends as the two hung out at Stockholm’s upscale Biblioteksgatan market, while Justin prepared for his sold-out concert that evening at the city’s Globe Arena. “They were talking the entire time,��? an eyewitness says of the pair, who nibbled on kabobs and wore similar jeans and sneakers. “Justin’s mom was even helping her pick out clothes at Urban Outfitters. And they walked everywhere��?- often arm-in-arm, says the witness!

After that happy interlude, Justin and Jess visited Oslo, Norway, on June 20, and Copenhagen, Denmark, on June 22, where they were seen jogging together. The love-fest continued after the duo arrived in Goteborg, Sweden. On June 24, they held hands while strolling around the city’s main gathering area, Avenyn. “They looked real cute,��? says candy store owner Cecilia Bengston. “It must be real love.��?

But the visit took a bizarre turn later that day. According to a European newspaper, Justin snapped at fans who asked him to pose for a photo at the city’s Hard Rock Café, and even asked on young admirer, “You want me to juggle, too?��? Then, the star reportedly locked himself on the roof of the posh Elite Hotel Stockholm Plaza and began throwing ping-pong, water bottles and strawberries while hurling obscenities down on the stunned crowd! “Justin spit on me!��? 17-year old Nino Antonio El-Khoury told the publication. Where was jess? She reportedly watched the scene in horror- before burying her face in her hands!

Still, she seems committed to standing by her man- and a source says she’s prepared to stay with him on tour for another two weeks. “She was so excited about visiting him that she went out and bought all-new outfits, several sexy sundresses and packed lingerie from Victoria’s Secret,��? says a pal of the bodacious actress. “Jessica likes to dress casually, so her friends are impressed that she bought a bunch of girly outfits to wear for Justin!��?
