It looks like things are getting real serious real fast between Jennifer Lopez and Alex Rodriguez!

The couple just started dating earlier this month, but she already met his family! The former baseball star’s sister Susy Dunand excitedly shared two selfies taken with the “Ain’t Your Mama” singer during some bonding time with her brother’s new fling.

“Any given Friday!” she wrote in the caption on Instagram, adding the hashtag “#Miscunis” — which is a Spanish term for “sister-in-law.”

Ever since news broke about their relationship, A-Rod and J.Lo have been spotted out together on a romantic couples vacation to the Bahamas before heading back to Miami together, E! News reported. Most recently, they were spotted out on a sexy date night at the Casa Tua restaurant in Miami where Jen showed off a ton of leg in a skin-tight white dress.

But even though it seems like she’s having a great time with her new beau, J.Lo’s friends are worried that she’s jumping into a new relationship too soon. Just until last month, she was linked to rapper Drake and a source told Hollywood Life that her pals are afraid she’s just setting herself up for another heartbreak.
