Madonna Hard Candy Concert (New York)

Madonna left little to the imagination as she ground her groin against young Justin Timberlake after slamming him into a wall at her Hard Candy New York concert. It was hard for us not to blush as the pair performed their eye-popping duet live for the first time on stage. With their 25 year age gap, it could easily have seemed like a drunken aunt getting a bit too frisky with the young lads at her nephew's party. But the Crazy For You singer, nearly 50, looked amazing as she vamped it up in dominatrix-style boots and a low-cut top. And judging by the grin on his little ferret face, Justin enjoyed every minute.

To squeals of delight from 2,000 fans, they writhed around while belting out their new single, 4 Minutes. The steamy duet came halfway through Madonna's sensational hour-long comeback gig at New York's Roseland Ballroom on Wednesday. She had flown us out to join her for the gig - a curtainraiser for her Hard Candy tour, later this year. Fortunately for Justin, her hubby Guy Ritchie stayed at their London home on childminding duties.

So he also missed his missus thanking young JT for making an old woman very happy. Panting, she said: "I feel like the luckiest girl in the world to have made a record with Justin, Timbaland, Pharrell and Kanye West."

She then strummed a few bars of Satisfaction on her black guitar, before joking: "You people thought you were coming to a Rolling Stones concert? F*** that!"

But the X-rated performance did leave her a little flustered. As she dedicated Hung Up to the fans who'd camped out overnight, Madonna royally cocked up. She missed a beat and glowered at her band as if it was their fault. Then she seemed to slip and fall on her bum leaving the stage. Oops! Not that anyone minded. From the moment she first appeared on a revolving M-shaped throne in a rhinestone encrusted tracksuit, the atmosphere in the tiny venue was electric.

Her slick routines with tightly choreographed male dancers got everyone waving their Hard Candy lollipops. Even for someone half her age, her energy was breathtaking. All hail the Queen of Pop - her reign's far from over.
