Ben Affleck showed off his skill on Sunday in Los Angeles as he demonstrated how to spin a basketball on his index finger while taking his son Samuel to a basketball game.

The 51-year-old Argo director and star tossed the basketball into the air and then demonstrated the spinning motion during a weekend outing with his youngest child.

The two-time Oscar winner, who is also father to daughters Violet, 18, and Seraphina, 14, with ex-wife Jennifer Garner, 51, wore a blue flannel top over an ash gray shirt and special edition Travis Scott Nike sneakers.

Samuel wore a purple basketball jersey with black shorts and red sneakers and carried a green water bottle.

Affleck, a New England native and Boston Celtics fan, has made no secret of his love of hoops, having appeared courtside at many NBA games and worked on a number of basketball projects.

The Good Will Hunting actor and his son were guest speakers in Salt Lake City during the NBA's All-Star Weekend for the Ruffles Celebrity Game earlier this year.

Earlier this year, he directed and starred in the sports drama “Air,” about Nike's 1984 signing of rising superstar Michael Jordan.

“Someone asked me what you're doing from Boston and making a movie about the Chicagoan,” Affleck told reporters in February, according to the AP. “Michael Jordan, I think, kind of transcends the rivalry.”

Affleck played a former basketball prospect turned coach in the 2020 sports drama The Way Back.

The Surviving Christmas star had a busy weekend as he and wife Jennifer Lopez, 54, welcomed a host of famous faces to a holiday party at their Los Angeles mansion.

Affleck and Lopez, 54 – mother of twins Emme and Maximilian, 15, with ex-husband Marc Anthony, 55 – “were both in such a good mood” that they “hosted a really fun party,” a source told People Sunday.

“The kids were all there dancing and having a great time, especially the twins and Violet,” the source said.

Stars like Margot Robbie, 33, Michael B. Jordan, 36, and Ben's younger brother Casey Affleck, 48, were among those in attendance at the celebrations, the source told the publication.
