Watch: Jennifer Lopez performs at iHeartRadio Pool Party [full HQ concert]...

As if Miami wasn't sweltering enough, Jennifer Lopez goes and sends temperatures soaring with a sizzling rump shaking set at last night's iHeartRadio Ultimate Pool Party.

The Nick Cannon-hosted gig took place at the Fontainebleau Hotel, which saw J.Lo performing old hits and new songs off her latest album 'A.K.A.' In doing so, she showed how much in great shape she was in while rocking a colourful plunging corset style leotard. 

I know that she gets flack for not being a very good singer. For most of her career, she's had to rely on her looks and sexy image to get on by. The problem is, a female artist with little singing talent may be able to get away with it below the age of 35 until the industry age bias kicks in. 

Therefore, is it still acceptable for a 45-year-old mother to be twerking and shaking her bootyful arse on stage?
