Cannes wasn’t the only starry city last week.

Robert Downey Jr. and his wife, Susan Downey, were honored at Lincoln Center’s Annual Spring Gala last Monday.

We’re told A-list guests at the event — including Daniel Radcliffe, Paul Bettany, and Matthew Rhys — enjoyed a special performance of “Man of La Mancha.” 

That same night, the Cinema Society hosted a special screening of the Hulu series “Rivals” at the Crosby Street Hotel. 

Stars David Tennant and Alex Hassell were there as well as executive producer Felicity Blunt, who is the sister of Emily Blunt and wife to Stanley Tucci.

Also that night, ABC’s Stacey Sager was honored at the 72nd Spirit of Achievement Luncheon hosted by the Women’s Division of Albert Einstein College of Medicine.

The celebration, held at the Rainbow Room, raised $1.4 million to advance medical research, including work tied to lung cancer research and blood-based early detection for dementia.

Last Tuesday, John Legend and Chance the Rapper hit the 20th Annual Gordon Parks Foundation Gala at Cipriani 42nd Street.

The event brought together changemakers across film, music, the visual arts, business and philanthropy to honor five key figures working at the intersection of the arts and social justice.

We’re told Lonnie Ali was recognized with an award on behalf of the Muhammad Ali Family, which was presented by Colin Kaepernick.

Meanwhile, Nick Jonas and Paul Rudd attended a special screening for their new movie, “Power Ballad.”

The movie’s director, John Carney, was also in tow.

The following evening, Tribeca Festival co-founders Robert De Niro and Jane Rosenthal held their press day to hype up the fest, which will include talks by Madonna and special screenings of “Cable Guy” and “Taxi Driver.”

Uptown, Katie Holmes was honored at the American Ballet Theatre Gala at Cipriani 42nd Street. We’re told the “Dawson’s Creek” alum was accompanied by her mom, Kathleen A. Stothers-Holmes, for the special event.

Katie Couric, Constance Wu, Zac Posen, Michael Imperioli were also there and the evening included a special abbreviated performance of “Don Quixote.”

Elsewhere in the Big Apple, Puerto Rican singer-songwriter Lenny Tavárez partnered with Ballroom Basix and the Boys & Girls Club of Harlem for a series of philanthropic community initiatives centered around music education, Latin culture and youth outreach.

The musician led a salsa workshop with Ballroom Basix students and then taught a songwriting and production class with the Boys & Girls Club of Harlem, inspired by his new single, “Pa’lo Bonito.”

In the last couple of weeks, megastars like Michelle Obama, Sarah Jessica Parker, Tom Hanks and Timothée Chalamet were seen at the Broadway show “Giant” at Music Box Theatre.
