On Friday, the "Ain't Your Mama" songstress celebrated her 47th birthday wearing a skin-tight Balmain jumpsuit that left little to the imagination. The brown one-piece featured sheer panels throughout, leaving JLo's sides almost completely exposed.
The mother-of-two kept accessories to a minimum, pairing the sexy jumpsuit with a simple pair of pointy-toed pumps and studded earrings. Her long locks were pulled back into a wavy ponytail, and she sported a sultry smoky eye and nude lip combo.
Joining Lopez for her birthday celebrations was none other than Kim Kardashian West and (gasp!) Calvin Harris. This is the first time we've seen the reality TV star and the DJ together, after Kardashian leaked videos of a phone call between her husband, Kanye West, and Taylor Swift (Harris' ex-girlfriend).
Kim even presented her "idol" with a birthday cake, following JLo's "Jennifer Lopez: All I Have" residency show at Planet Hollywood in Las Vegas.
Looks like a fun night! Happy Birthday, JLo!
