Alex Rodriguez, ever the supportive boyfriend, stood by bae Jennifer Lopez’s side as she closed out her 3-year Las Vegas residency on Saturday night. Of course, he documented the affair on social media.

If you’re unfamiliar with the former MLB player’s Instagram page, here’s the gist: it’s basically a J. Lo fan page. He’s so proud of his Bronx-born gal, and he just wants the world to know!

In the last two days, Rodriguez has posted not once, but three times — each of which focused on his girlfriend’s Vegas sign-off (one of said posts was a video montage of J. Lo lifting weights to “Ain’t No Mountain High Enough” — I kid you not).

Anyway, the most recent of A-Rod’s J. Lo-affiliated posts included him, Jen herself, and fellow sports legend Kobe Bryant and his wife, Vanessa.

In the photo, Lopez is shimmering in a rose gold jumpsuit while Rodriguez stands behind her clad in a suit in the least subtle shade of pink imaginable. Though we’re all for couples coordination, one of A-Rod’s daughters wasn’t quite as jazzed on his look. As documented by Rodriguez himself, one of his daughters (Natasha, 13, or Ella, 10) knocked him down a few pegs with the cutting question of all cutting questions: “What are you wearing?”

Confidence shot, A-Rod asked his fans to back him up: “I decided to bust out the pink suit for the final show of #AllIHave. What do you think? Comment a 👍 if you’re a fan of this look. #RealMenWearPink #RoseToTheOccasion.” Ah, dads …
