After months of speculation, Jen went Insta official with Ben after breaking up from her ex-fiancé Alex Rodriguez.

She took to her Instagram account to share a string of pictures of herself posing in a bikini and one of her locking lips with Ben.

In the caption, Jennifer appeared to be celebrating her 52nd birthday on Saturday.

"5 2 … what it do …" she wrote alongside the snaps, adding a pink love heart emoji.

Her followers rushed to comment on the snaps, with one writing: "We are living for this."

Another posted: "I mean, if you’re going to Instagram official do it like @JLo."
