Jennifer Lopez turns 45 today (July 24)! A big happy birthday to the "I Luh Ya Papi" singer is in order!

What better way for the star to celebrate over the last few days than hanging out with best friend Leah Remini and their kids - and J-Lo has just posted a new video on Instagram of the group's shenanigans!

In the funny Instagram video, Jennifer Lopez and Leah Remini filmed themselves in the car (something we've seen them do before in Instagram moments!) with their kids in the back seat. The pair bopped their heads while Leah sang.

"About to do a little horseback riding! Are you gonna do it?" Leah Remini asked J-Lo in her song.

When Jennifer quickly replied "No!" to her friend's question, her bestie was unimpressed!

"Damn it J! Really? You have to!" argued Leah.

"No, but the kids are gonna do it!" said J-Lo.

Jennifer Lopez posted the funny video to Instagram with a mention of a possible update.

"Out to do a lil...lalala #mommytime #horsebackriding #familyouting #willshegetonthehorse #staytuned," wrote J-Lo in her caption.

Time will tell if the superstar singer took on Leah's challenge and went horseriding with the kids!

Just last week in other Instagram escapades, Leah Remini filmed herself talking and then turned the camera on J-Lo, who was dressed up to the nines for some casual poolside relaxing.

"Jen asked me to meet up by the pool right. Here's me, normal," said Leah. "Look at this one. Head wrap. Jewellery. Can you be ugly once? Can you be normal once? You're such a jerk off!"

The pair laughed it off in the video, which came after a series of fun peeks into Jennifer Lopez's latest vacation in the Hamptons.

"Attacked at my own damn pool by @leahremini! #summerfun #besties #canubenormal #noIcant #gottakeepitsexy #familia," J-Lo captioned the Instagram video.

J-Lo clearly didn't hold any kind of grudge against her gal pal, despite the attack on her poolside ensemble. Not long after posting Leah Remini's video on Instagram, Jennifer posed for a snap in a sexy red bikini. She had dropped the head wrap, but the fab gold earrings were still noticeable in the pic.
