Numerous social media posts from party guests made their way online during the event as they helped Lopez celebrate her happy day, Us Weekly reported. One source told the publication that the sexy singer and Chmerkovskiy looked "super-cute" together at the party.
The Ukrainian dancer didn't show up until 1 a.m. because he had rehearsals for the upcoming Sway event, but he wanted to be there since Lopez personally invited him. The pair has been fueling romance rumors for some time, although both insist they are just pals.
Montana, who collaborated with Lopez on "I Luh Ya Papi," brought his girlfriend Khloé Kardashian and the pair hung out with Scott Disick all night. Montana also posted a couple of photos of himself with JLo as well as with Disick and rapper Fat Joe.
Kardashian also shared a photo of herself with the newly single pop star, captioned with, "She served it last night!!! Happy birthday @jlo."
Other celebrities at the bash included Leah Remini, who is Lopez's best friend and the one allegedly responsible for introducing her to Chmerkovskiy. Russell Simmons, Tracy Anderson, Kristin Chenoweth, Rachel Zoe and Brian Atwood were also there. Benny Medina, who is Lopez's manager, gave a sweet speech to the singer, saying, "It's not the years we live in life, but what we make of it."
The lucky guests all indulged in a huge cake that was made into a mold of Lopez leaning on top of a lion, which everyone enjoyed, along with the festivities that went on until 4 a.m.
