"They were super-flirty and very happy, kissing and cuddling." an eyewitness told OK!.
Although Lopez and Smirnoff were the last people to leave the restaurant, OK! reported they still continued the flirt-fest and moved to neighboring club Kiss & Fly for post-dinner drinks.
If Lopez and Smirnoff do intend on giving their relationship another go, at least they'll be located on the same coast.
Smirnoff was recently paired with former The Restaurant star and upcoming Rocco Gets Real star Rocco DiSpirito for Dancing with the Stars seventh season; while Lopez will take over as weekday host for Extra beginning next month.
