Lance Bass bought Kris Jenner a "dirty" gift for her birthday.
The former *NSYNC star wasn't able to attend the matriarch's star-studded 60th bash over the weekend but made sure he and his husband Michael Turchin gave her something "very meaningful" to mark the milestone.
Speaking to the New York Daily News' Confidenti@l page, he said: "She doesn't need anything (but) she's one of our best friends so it's all about the meaningful things so we sent her something very meaningful the day of her birthday."
Pressed on what he splashed his cash on, the handsome singer, who's a close friend of the family, refused to divulge too many details because it was too naughty to share.
He said: "It's a little dirty, that's why I can't tell you why."
Asked whether he bought her a sex toy, he scoffed: "No but that's a good one for next year!"
Meanwhile, the 'Keeping Up With the Kardashians' star - who turned 60 on November 5 - was thrown a huge 'Great Gatsby'-inspired bash at The Lot in West Hollywood on Friday (06.11.15), where she celebrated her milestone and danced the night away with her famous daughters.
As well as her children - Kim, Kourtney and Khloe Kardashian and Kendall and Kylie Jenner - other guests in attendance included Boy George, Will Smith and wife Jada Pinkett Smith, Melanie Griffith, Chrissy Teigen and John Legend, Tommy Hilfiger, Kyle Richards and Lisa Rinna.
