Lady GaGa has plenty of reasons to celebrate these days. The international pop sensation has two No. 1 singles, and a new beau! In Touch can exclusively reveal that the “Just Dance” singer is dating a 29-year-old LA entrepreneur named Speedy. The couple, who first met on the set of her music video “Love Game,” has been dating for about a month.“They were just friends for a while, but recently things got serious,” an insider tells In Touch. “They have a lot in common and are totally crazy about each other.” Though the romance is brand new, the two have been inseparable in recent weeks. The star, born Stefani Germanotta, kissed her new man on the set of her music video “Paparazzi” in Malibu on April 12. The next day, the pair engaged in some PDA at Katsuya in Brentwood where they were “all over each other, cuddling in the corner,” an onlooker tells In Touch. It looks like Speedy might be in for the long haul. According to the insider, Lady GaGa has asked him to to join her on her Fame tour, which ends in September. “He makes her really happy, and they are having fun right now,” the insider adds.
