Shake it, baby! Jennifer Lopez takes to the stage at the iHeartRadio music festival in a red tasseled outfit that flashed her famous derriere during a very vigorous dance routine

The 42-year-old strutted her stuff and left her backing dancers gaping in her wake as she shook her bottom – and then flashed it to her delighted backing band.

Jennifer was performing on the second and final day of the festival, which took place at the MGM Grand Garden Arena in Las Vegas.

You go, girl! Egged on by her wolf-whistling backing dancers, Jennifer wiggled and shook her curves and tassels

She performed a red hot set that include her new single Papi, and other hits including Get Right, On The Floor, Let’s Get Loud, Ain’t It Funny and her classic, Jenny From The Block.

And it proved to be a busy weekend for the star who jetted in from the set of her new film Parker in Boca Raton, Florida, to perform at the event.

She was one of many acts that performed at the two-day festival, including Lady Gaga, Steve Tyler, Nicki Minaj, Nicole Scherzinger, Sting and Usher.

She also spoke about her male alter-ego Joe Caldone and ‘his’ appearance at the MTV Video Music Awards last month.

Speaking to host Elvis Duran, she said: ‘Who does he think he is going on national television and speaking about my personal life like that? He’s a sucker.’

And in a rather poignant moment, she dedicated her song ‘Hair’ to Jamey Rodemeye, a 14-year-old boy who committed suicide after being incessantly bullied at school.

The youngster, who was from Buffalo, New York, was found dead after an apparent suicide last week having posted in a blog for months about the bullying and how people would launch gay insults at him.

Before he died, he posted a lyric from Lady Gaga’s song The Queen on his Facebook page which said: ‘Don’t forget me when I come crying to heaven’s door.’
