Britney last hosted the event – at which Scandinavian brands are showcased – on Dec. 1. At that party, she was presented with a birthday cake and bumped into her one-time BFF Paris Hilton.
"Britney has said 'yes,' to hosting it," Claus Hjelmbak, the Danish businessman who founded the event, tells PEOPLE. "I am beyond excited because the experience she gave everyone in December was amazing. She absolutely made my event."
Hjelmbak, who was at Spears's side when she and Sam Lutfi went on an early morning shopping spree Jan. 17 at Kitson in L.A., told PEOPLE of the outing: "I know people will say it's weird she was shopping at 2 a.m., but [Kitson] said you guys can always come when you want. I just called the owner and said can we come over and they said 'sure.'"
Hjelmbak also has kind words for Lutfi, saying, "He's the most down-to-earth, easy-going guy. He doesn't have a bad bone in his body." As for Adnan Ghalib, he said, "I don't know him."
As for online reports claiming Spears has multiple personalities, Hjelmbak, who first met Britney in 2006, says, "I have only seen one person and that's the Britney I first met and seen every time. She's a very sweet person."
