Jennifer Lopez enjoyed multiple birthday parties.
The singer and actress, who turned 44 on Wednesday (24.07.13), has been celebrating all week with her boyfriend Casper Smart and her five-year-old twins with ex-husband Marc Anthony, Max and Emme.
A source told UsMagazine.com: "Her birthday was so much fun and she's still celebrating. Casper is fantastic and they are in a good groove right now and the kids are adorable. All is well but things have just been busy!"
The former back-up dancer, 26, posted a touching message about Jennifer on Twitter for her birthday, writing: "HAPPY BIRTHDAY to my very very beautiful bear the nicest, sweetest, funniest, sexiest bear there is! Love u."
The brunette beauty kicked off her celebrations with an American-themed barbecue in The Hamptons, New York, on Saturday (20.07.13).
The 'Dance Again' singer was joined by several of her famous friends including Alicia Keys and record executive L.A. Reid for a family-friendly fun day.
The partygoers demolished "lots of mojitos" on the estate of Jennifer's $10 million mansion, and the event also featured a trampoline and an array of party games such as water balloon fights and a sack race.
Earlier this year, Jennifer gushed about Casper and explained why he is her perfect match.
She said: "He's fantastic; he's like my best friend. I can tell him everything, when I'm feeling down, when I'm feeling good. He gives moral support, endless love and support."
