Lady Gaga is asking Pippa Middleton for tips on how to act like a royal. The pop singer reportedly wants the socialite - sister to the Duchess of Cambridge, who is married to Britain's Prince William - how to conduct herself with more grace, after reading her new book on party planning, Celebrate.

"Gaga is obsess­ed with the royal family and espec­ially with Pippa. She was so desperate to get her hands on Pippa's Celebrate book she had aides ship it to her via courier to Puerto Rico where she was performing earlier this week. She hopes it will help her throw better parties and teach her how to be more like a member of the royal family," a source told The Daily Star.

Gaga, 26, is also said to be keen to strike up a friendship with Pippa. "By reading the book Gaga hopes it will give them something to talk about should they ever meet up. She would love to get pally with Pippa. She's been intrigued by her since the royal wedding," the source added.

Gaga has made no secret of her affections for the royal family, previously saying the late Princess Diana was one of the "most important" people in her life growing up, and writing a song in tribute to her, "Princess Die."
