He may be one of Hollywood's most sought after talents, but even Matt Damon takes out time of his busy schedule to catch his kid's sports games.

On Sunday, the 46-year old actor was spotted in Los Angeles cheering on his stepdaughter Alexia - who he refers to as his own daughter - during her soccer game.

The Martian actor dressed practically, wearing a grey beanie and warm black layers during the game.

The father of four smiled as he watched the game from the stands accompanied by several friends.

He kept warm, sporting black boots, dark pants and a light zip-up hoodie during the match.

A simple wedding band and several bracelets could be spotted on the star's hands from afar.

After the game the avid humanitarian stepped onto the field to greet daughter Alexia Barroso, who is actually his wife Luciana Barroso's child from her first marriage.

The Good Will Hunting actor congratulated the 17-year-old with a big hug as the two chatted.

After giving his daughter some post-game congratulations, the Academy Award winner walked away with his eldest offspring and their friends.

In addition to teenage daughter Alexia, Matt and his wife of over a decade have three other kids together: Isabella, 10, Gia, eight, and Stella, six.

The pair met in 2003 were wed in a private civil ceremony in December 2005 in New York. 

Damon considers himself fortunate to have led a mostly private life with his family, explaining in a 2015 USA Today interview that he likes to fly under the radar.

'I attribute a lot of it to luck. [Paparazzi members] shoot me every day coming out of the gym... [but a] married guy with kids? It's not that exciting.'
