Justin Timberlake & Jessica Biel Take Manhattan!

Talk about a chic pair! A dapper Justin Timberlake shares an inside joke with Jessica Biel at the Metropolitan Museum Costume Institute gala on May 3. "They're both very funny and creative," Timberlake's mom Lynn Harless told PEOPLE.

Earlier that same day, the couple kept it casual with an affectionate hand-in-hand stroll through their Tribeca neighborhood. "I get pretty romantic around her," Timberlake once admitted.

Sans Timberlake, Biel fulfills her duties as a Revlon Global Brand Ambassador at the 13th annual Entertainment Industry Foundation Revlon Run/Walk for Women in Times Square on May 1, where she was joined by Halle Berry and Jessica Alba.

A day after Biel's charitable walk, Timberlake leads his lady out of Richard Rodgers Theater, where they checked out the Tony-winning musical In the Heights on May 2.

Days later, Timberlake and Biel take in another Broadway musical, Memphis, posing with the cast backstage at Shubert Theater. "Justin kept his hand on Jessica's back the whole time," a show insider told PEOPLE.

Timberlake takes the lead once again for brunch babe Biel, after having a bite at Tribeca eatery Bubby's Restaurant on May 5.

In his-and-her athletic gear, Biel and Timberlake – who both stay fit with the help of personal trainer Jason Walsh – rev up their routine for a joint couples workout in downtown Manhattan.

The glowing couple are in good spirits as they take a casual stroll through the West Village on May 2. "It's the most precious thing that I have in my life," Biel told Vogue of her relationship in January.
