Jennifer Lopez and Alex Rodriguez celebrated their birthdays this past weekend.

The couple had a joint birthday celebration and took to social media to express their happiness and birthday celebrations. Jennifer Lopez's birthday is on July 24 and Arod's is three days after that. However, the couple celebrated for days and intend to continue to do so.

"They are really into each other and A-Rod constantly tells her how amazing she looks and is. She is super happy being with him and the kids really love him," a close friend of Lopez said. "We're all so pleased she's with someone who finally has their own s- going on. So there's no competition between them. A-Rod is so smart with business. He's a huge investor, so she respects him and asks him for advice all the time. With Casper, she could not do that, so this is great." All eyes were on Lopez since she wore an incredibly stunning sheer black dress, which revealed her entire back. Rodriguez wore an all blue suit and was seen with Lopez the whole entire time.

On Monday, Lopez shared several posts on Instagram and showed off the tower of a cake she had. She also posted photos with Rodriguez getting rather intimate.

It looks like the celebration has just begun with the happy couple and more photos are to soon be expected.
