ANNA’S ACE OF HEARTS

Forget Prada – it looks like this season, the devil is into Roger.

Imperious Vogue editrix Anna Wintour is apparently crushing like a Teen Vogue intern over hunky tennis star Roger Federer.

She’s been dressing him up. She threw a fancy party for him at the Gramercy Park Hotel after she got him on the cover of Men’s Vogue.

And on Wednesday night, the hardboiled magazine mistress was front and center at his U.S. Open first-round match, flashing a schoolgirl-like smile as he easily beat Chilean Paul Capdeville.

It was second time this week that she’d gone to one of Federer’s matches. Asked by The Post if she had a thing for the tall, dark and handsome Swiss star, Wintour laughed.

“Oh, sure, right. I just like his tennis game,” she said before being whisked into the VIP entrance at Arthur Ashe Stadium in Flushing.

Wintour sat in Federer’s private box. One row in front of her sat designer Oscar de la Renta, another one of the Federer’s pals.

“She’s really helped get him into the world of fashion and has influenced how he dresses, both on and off the court,” said Federer’s spokesman, Tony Godsick.

There’s no indication that it’s anything beside mutual admiration between Wintour, 57, and Federer, 26, who has been dating former tennis pro Miroslava “Mirka” Vavrinec since 2000.

“Anna is a big fan of the sport and always has been,” Godsick said. “Roger is always interested in fashion, and obviously they’ve become friends.”

Nevertheless, courtside wags at the Wednesday match couldn’t help but notice the sunny glow that came over the normally icy Wintour, who is said to have been the inspiration for the tyrannical Miranda Priestly character in the novel and film “The Devil Wears Prada.”

“She seemed to be happy [at Wednesday’s match]. What’s come over her?” noted New York magazine’s blog.

The only thing that’s certain is that Roger’s fashion sense is definitely getting a lift.

On Wednesday he ditched his normal blue tennis togs for a more sophisticated black ensemble that would not be at all out of place on a Bryant Park runway.

“I thought it really looks cool,” he said. “In New York you can do such a thing – nowhere else in the world. I really thought it looked good.”
