Jennifer Lopez and Maksim Chmerkovskiy dating rumors show now sign of slowing. Especially when the two stars keep dancing on the rumors feeding the frenzy. Jennifer Lopez and Dancing with the Stars Pro Maksim Chmerkovskiy deny the rumors, kinda, while hitting the town.

Jennifer Lopez celebrated her 45th birthday with Maksim Chmerkovskiy. Oh, there were other friends, like Khloe Kardashian, at the star-studded bash. But who noticed? Not during the same week that Dancing With The Stars Maksim Chmerkovskiy said being called Jennifer Lopez's boyfriend was "unbearable."

Jennifer Lopez celebrated her 45th birthday at Hamptons hotspot Nammos on July 24. Jenny from the Block hosted 100 high profile guests, none from the block, including French Montana, Khloe Kardashian, and Scott Disick. But all media eyes were on Jenny and Maks.

Us Magazine quoted an eyewitness who said Lopez and Chmerkovskiy were "super cute" at the party.

Maksim recently told celebrity site Confidenti@l "I now understand why Hollywood is such a difficult place to have a good relationship in: because there's all these interferences. Two people have to be so strong - and notice I didn't say 'in love.' They have to be in love, but trust me, there've been situations when two people have been really in love, and all of this gets in the way and it completely ruins it."

Chmerkovskiy and Lopez met in November 2013, when they performed together at the American Music Awards. Lopez, whose break-up with dancer Casper Smart was revealed on June 6, had earlier denied that she was dating anyone.J.Lo and Maks shared a dance during Lopez's  tribute to Celia Cruz. At the time Lopez was still going out with her former backup dancer Smart. Maks was dating model Kate Upton. Maks and Kate broke up weeks later. Kate Upton and Maksim Chmerkovskiy split after six months together.
