Jennifer Lopez showcases flat belly in turtleneck crop top as she leaves auction house hand-in-hand with beau Alex Rodriguez

They've been going strong since spring.

 

And Jennifer Lopez and Alex Rodriguez looked like they were taking their relationship quite seriously Thursday, seen linked by the hand after a trip to Christie's art auction house.

The 48-year-old beauty was ever-chic in a textured green sweater which displayed her taut tummy along with matching paper-bag pants slung low across her hips.

Going steady: Jennifer Lopez and Alex Rodriguez looked like they were taking their relationship seriously Thursday, seen linked by the hand after a trip to Christie's auction house

It's possible the pair were thinking about the next step and doing some joint apartment decorating together. 

While out, the triple-threat threw a long camel coat on the outside while accessorizing with a matching newsboy cap and olive heels.

JLo carried a stylish green hobo in a ring adorned hand while giant diamond studs completed her look.

 

Besides her, Alex looked sharp in a grey tartan coat worn above a well-tailored charcoal suit.
