Pretty in pink: Jennifer Lopez, 46, put on a very busty display and showed offer her toned limbs in a racy pink mini dress on the set of American Idol on Thursday

The beauty’s sleek caramel tresses cascaded over her shoulders and she sported a deep tan.

And the eye-catching outfit certainly put smiles on the faces of those working on set. All eyes were firmly on the star as she made her way into the studio to take her place on the judging panel.

The garment’s cut out sides ensured Jennifer’s slender curves were visible, and the in-shape star had every reason to be confident with her enviable physique.

Before she changed into the saucy number, Jennifer popped out of her dressing room in a pale blue covering gown while sipping a fizzy orange drink through a straw.

When she reappeared, it was quite the transformation with the singer clearly pleased with her look. And as she prepared to go in front of the cameras, she flicked her tresses out for one final adjustment.

American Idol hopefuls Lee Jean and Avalon Young went crashing out of the competition as the field for the Top Six was set.

Lee, Avalon and Sonika Vaid were forced to sing-off for the final place in the next round of the show and the judges decided to keep faith with Sonika and kept her dream alive for another week.

‘It gets harder and harder every week and I have to say that this group is phenomenal but the save goes to Sonika,’ said Harry dramatically as she mouthed her thanks to the judges.

First La’Porsha Renae and Trent Harmon performed ‘See You Again by Wiz Khalifa featuring Charlie Puth.

‘It was the perfect song and played to both of you strengths and you worked really well together, it was collaborative and great,’ said Keith Urban.

Jennifer Lopez called the performance ‘Magical’ and Harry Connick Jr. told them their voices had blended very well.

Roommates Sonika Vaid, 20, and Avalon Young, 21, teamed up to perform ‘Rise Up’ by Andra Day.

Jennifer told them that their voices were ‘So Angelic’ and that they had pushed each other to a high level of performance but told each of them to loosen up on stage.

Harry said that Avalon had the advantage in the rhythmic song but praised Sonika’s ‘Breathtaking’ voice, while Keith praised Avalon as an ‘Effortlessly natural’ singer.

Dalton Rapattoni, 20, and MacKenzie Bourg, 23, then got together to sing ‘I Want It That Way’ by the Backstreet Boys.
