Yesterday, hot mama Jennifer turned 45 (yes... we can't quite believe it either!) and it seems Keeping Up With The Kardashians star Khloé was on hand to help her celebrate her special day.
Sending the star her wishes, Khloé posted a snap of the pair posing alongside each other, with the caption: "She served it last night!!! Happy birthday @jlo".
Reality star, Khloé, who recently sparked pregnancy rumours by posing with her hand on her stomach, can be seen flaunting her best pout as she stands next to the pop diva.
And of course like a pro, a sultry J.Lo knew exactly how to work the camera!
Last month, Khloé and Jennifer were spotted enjoying a night out together after J.Lo's homecoming concert in the Bronx, New York. After watching her man French Montana perform with the 'Jenny From The Block' singer on stage, Khloé joined them for a fun-filled evening.
Helping J.Lo to celebrate once more, Khloé and her beau attended the Latina beauty's birthday celebrations in the Hamptons last night.
So far Jennifer hasn't actually revealed how she celebrated her birthday, but judging by her latest Instagram pics it all seemed super-glamorous.
The birthday girl looked party ready as she posed for a selfie looking ultra-hot with her hair in big, voluminous curls (before sweeping them up into a sleek pony later on) and sporting a stylish white bralet.
Sharing her pre-party snap the star wrote: "Let the games begin! #itsmyparty #funtimes #birthdaygirl #aintnothingbutanumber."
And like Khloé, J.Lo's ex-boyfriend Casper Smart also made sure to send his birthday wishes to his former flame. Taking to Twitter, Casper tweeted: " "Happppppppy Birthday to the most beautiful lil bear in the world!!!! May all your wishes come true!! @JLo."
Happy birthday Jen!
