So, with the aim of bagging herself a royal customer, Britney plans to do what any er, savvy businesswoman would - she's going to pop the entire collection (which includes vintage-inspired bustiers, kimonos, camis and sleepwear) in the post to the Duchess of Cambridge. Yes, really.
The 32-year-old star revealed the news at a launch party for her new project in London on Tuesday.
"I would love to see Kate in my underwear designs," she told the Mirror.
"That would be splendid. I'm going to send her one of every piece. So she'll have plenty to choose from."
And her list of dream celebrity clients doesn't stop there.
"I'd love to see Gwen Stefani modelling my collection," Britney added. "I think she's very cool and sexy." Clearly, she's aiming high.
So, what can Kate and Gwen expect to see from the collection? Luckily Britney's given everyone a sneak preview by posting pictures on Instagram in the lead up to the launch...
"Every woman should feel confident and beautiful in everything she puts on," she said of her lingerie and sleepwear range.
"My vision... is to create pieces that are sexy, luxurious, and comfortable at the same time."
They're affordable too - the collection is priced between £11 and £46. Let's just hope Kate appreciates her present from the pop princess.

She's come a long way since her 'Oops! I Did It Again' days...
