Washington, July 11 : Hollywood actor Matt Damon plays a "stalkerish" in `Entourage', says show''s star Adrien Grenier.

According to TV Guide, the `Ocean''s Eleven' star recently shot for the cameo in the hit HBO series' season finale.

In his cameo, the star does whatever it takes to get donations for his real-life charity.

"The joke is that Matt is very passionate about his charity -- almost in a stalkerish kind of way," Usmagazine. com quoted Grenier, who plays movie star Vince, as saying.

"Vince becomes intimated by his intensity. He ends up bullying Vince into giving much more than he should," he added.

Co-star Emmanuelle Chriqui, who plays Sloan, added: "Matt gets Vince to make a massive donation. He''s like, ''Bro - whip out your checkbook!''"

NBA player Lebron James also appears in the finale alongside Damon.

"Lebron and Matt have a scene together, and they just kill it!" said director Doug Ellin. (ANI)
