Adam Lambert and boyfriend Sauli Koskinen were packing on the PDA at the launch of J. Molinari sponsored by BluCigs and Hpnotiq harmonie.

Aside from jewelry designer Markus Molinari's new line of jewels, it was also his birthday celebration. Double the reason to party! The big event was hosted by John Terzian of The h.wood Group.

We're told Glambert and his boy sipped on Hpnotiq Harmonie "Only Gurl" drinks and yummy Crumbs cupcakes. Sounds delish!

See the sexy couple posing with Mr. Molinari ... after the jump.
