The pooch is technically both of theirs, but we can guess who plunked down the cash!

Casper Smart ran errands in L.A. and brought the couple's adorable boxer puppy Bear with him, and we guess if his choreography career doesn't work out he can always fall back on being a professional dog walker!

The tatted backup dancer was toting a Sephora bag, so we're inclined to think he picked up some beauty products for Jenny from the Block. Now we see why she keeps him around... she doesn't have to pay another assistant!

To his credit, we haven't seen the former American Idol judge this happy in a very long time, so we have to believe he treats her like a queen. Not only that, but he's proven to be great with her twins Max and Emme, and nothing makes a woman fall in love quicker than a man who loves children!

Little Emme was out with the nanny the other day, and we love how she's literally a mini-J.Lo in her purple Adidas track suit!

Va-va-va-voom!

Jennifer Lopez and her much younger beau Casper Smart sizzled at the Vegas promotional screening of Parker.

In the flick, JLo plays a real estate agent who's going through some personal shiz. Good thing she has a strong shoulder to lean on with co-star Jason Statham.

The sexy Latina's Kaufman Franco gown is to die for!

No wonder Casper Smart is lovin' life! The 25-year-old dancer gets to shop at Harrods in London with his mega-successful 43-year-old girlfriend Jennifer Lopez.

No doubt, he gets to buy anything he wants!

The sexy twosome kept it casual while spending JLo's dough. We're lovin' how the curvaceous Latina paired her melon-colored sweatsuit with a pricey bag.

These lovebirds still seem to be going strong!

Jennifer Lopez is taking in the sights and sounds of New York with her young boyfriend Casper Smart.

The hot couple returned to the Tribeca Hotel in the Big Apple after taping a segment for The Katie Couric Show.

While in NYC, JLo, 43, and Casper, 25, also hit up the Broadway play Evita starring Ricky Martin.

Great to see these two lovebirds still going strong!

Is J.Lo's boy toy hiding a big secret from his lady love? If you believe fellow dancer Josh Ayers, the answer is yes...

Ayers is a performer at Boulevard3 - the same club Casper Smart used to dance for - and he claims Jennifer Lopez's rebound romance is a sham, because her beau is secretly gay and using her for fame and fortune.

Ayers has made repeated attacks against Smart on his Twitter account, posting these pictures in March with the caption, "Check out Ur boy... And his low key homo ways." Smart is seen posing shirtless while donning gold hot pants, a neck scarf, and a suggestive bulge in his pants, but we're inclined to believe this pic was taken out of context!

We think this is a classic case of jealousy, because there's no fooling someone like Jenny from the Block!
