As she strutted out into the spotlight in front of hundreds of adoring fans, the star showed off her enviably long legs, which as always were toned to perfection.

Jennifer appeared to arrive at the annual bash solo, however, the star is no longer a single lady as she recently rekindled her relationship with Casper Smart.

The couple split last year amid cheating rumours, but some reports have suggested the break-up was merely a publicity stunt.

Celebrity gossip website TMZ claim that the star fabricated the separation purely to promote her movie Boy Next Door.

While reports have not yet been confirmed, the singer refused to deny rumours when she was spotted out and about on Friday.

However, despite the speculation, Jennifer appeared to be in high spirits at the Kids’ Choice Awards the following day.

She made an appearance at the show, which was held at The Forum, to present Nick Jonas with the Favourite Male Artist gong.

However, despite being delighted to hand over the award, the singer was eager to keep her distance from the star when he then got drenched in slime.

The pair were seen posing backstage together afterwards but she made sure there was no contact with Nick as she tried to protect her designer dress.

Nick hosted this year’s Nickelodeon channel’s fan-voted awards, which honoured the group Fifth Harmony as favourite new artist and Liam Hemsworth and Jennifer Lawrence of The Hunger Games: Mockingjay Part 1 as favourite action stars. The film was voted favourite movie.

Other winners included Emma Stone, who largely escaped its trademark slime when she accepted the best actress award for her role in The Amazing Spider-Man 2, and favorite family TV show Modern Family, whose stars including Jesse Tyler Ferguson didn’t get away clean.

Performers included Iggy Azalea with Jennifer Hudson and 5 Seconds of Summer, which ended up taking a goo hit.

Nick opened the ceremony by noting that One Direction was minus a group member with the exit of Zayn Malik.

‘A tough week. … Lot of girls in the house tonight still struggling after One Direction became Two Direction,’ he said, then asked, jokingly, ‘What’s next? Fourth Harmony? 3 Seconds of Summer? No, no. The Jonas Brother?’

One Direction didn’t appear to accept its trophy as favorite music group.

Others taking part in the ceremony included Jamie Foxx, Meghan Trainor, Chris Rock, Kaley Cuoco-Sweeting, Kevin James and Little League Baseball sensation Mo’ne Davis.
