The sultry thesp and N’Sync-er have been house hunting in Chelsea.

Jess and Justin were "quite impressed" with the palatial digs at The Lion’s Head Building, according to The New York Post.

The west side digs has 3 bedrooms, two baths and 16 foot high ceilings.  The 2,224 square foot duplex loft is currently listed for only $2.9 million.  And the current owner will throw in all the furnishings plus chandeliers and five state-of-the-art TVs for an extra $10K.

Justin went gaga over the funky Finnish sauna which he said was "smooth".

And when there’s the pitter-patter of baby feet in the power couple’s future,  Danny DeVito can baby sit.  The renowned producer/liqueur fancier is their neighbor in the building.
