Winter wishes, fairy tale dreams as LINDSAY LOHAN’s schoolgirl fantasies becomes a scheme to get horizontal with randy Prince Harry!

LINDSAY LOHAN has set her sights on the world’s most eligible bachelor – Britain’s Prince Harry!

And it’s not because the “Mean Girls” star wants to be a princess. Insiders say Lindsay is just looking for a royal romp.

The fact that hunky Harry, 29, has been involved with beautiful blonde socialite Cressida Bonas, 24, doesn’t seem to faze Lindsay as she’s been busy devising schemes to rub shoulders with the handsome prince.

And in a hilarious twist, The ENQUIRER has learned the 27-year-old actress is considering having a butt-lift because she’s heard that Harry is a fan of beautiful booties.

“Lindsay has always had a huge crush on Harry,” said an insider. “She drools over him whenever he’s on TV and goes on and on about how physically perfect he is, how she loves his accent, and what an amazing match they’d be between the sheets.

“She’s like, ‘If I could just get to meet him one time I know he’d go for me!’”

The troubled actress, who’s been in rehab seven times, was raking in cash – up to $15,000 a time – by making appearances in London nightclubs. Then, she took a break in January to attend the Sundance Film Festival in Utah.

But the insider expects her to head back to London soon, where Lindsay – who’s had her way with such Holly­wood hotties as Jude Law, Heath Ledger and Colin Farrell – will continue her “networking” among the city’s elite social circles to finagle a meeting with the prince.

Unfortunately for LiLo, Harry seems to prefer blondes to redheads as his list of rumored romances includes longtime Zimbabwean beauty Chelsy Davy, “Real Housewives of D.C.” star Catherine Ashley Ommanney, British socialite Astrid Harbord, model Florence Brudenell-Bruce and singer Mollie King.

Still, Lindsay remains determined to bed the dashing royal.

“She’s convinced Harry will eventually fall for her charms,” added the insider. “The way she sees it, they’re both cut from the same cloth – party-loving, high-maintenance A-listers who demand a lot of satisfying.

“She really wants to have him as one of her bedpost notches – and she’ll do almost anything to make it happen.”
