WASHINGTON – Forget a 20 percent tip. JT goes up to 30.

The Baltimore Sun says Justin Timberlake recently left a $100 tip on a $300 bill at Phillips Seafood in Baltimore. The singer ate in a private dining room with four other people, and reportedly ordered an $84 “clam bake for two,” which includes two lobsters, snow crab legs, shrimp, clams and more.

Timberlake was in town to co-headline a Thursday night concert with Jay-Z.
