Ciara is still rocking her 'Body Party.' The R&B songbird beat J. Cole's self-esteem anthem 'Crooked Smile' featuring TLC as the Hottest Summer Song to remain the victor for the third week in a row.

'Body Party' nabbed 55 Percent of the vote to Cole's 45 Percent in the latest Hottest Summer Song poll. This week, CiCi will face off with a major challenger in the rap game -- Jay Z.

Arguably, Hov's double-platinum opus 'Magna Carta Holy Grail' was one of the hottest albums of the summer. The collection boasts the fine-arts banger 'Picasso Baby' and the braggadocios 'Somewhere in America.'

One of the album's highlights is the kick-off track 'Holy Grail' featuring Justin Timberlake. On it, Jay spits a myriad of rap quotables about being hip-hop's biggest rap star.

"Now I got tattoos on my body, psycho bitches in my lobby / I got haters in the paper, photo shoots with paparazzi / Can't even take my daughter for a walk / See 'em by the corner store / I feel like I'm cornered off, enough is enough, I'm calling this off," he raps.

The video is equally compelling with its dramatic visuals and both Jay Z and JT's verses are flipped in reverse.

So which one is the better summer jam? Is it Ciara's seductive ballad or Jay Z's anthem 'Holy Grail'?
