Mark Wahlberg shows Justin Bieber 'Entourage'

Singer Justin Bieber was treated to a special screening of the "Entourage" film by Mark Wahlberg and he has praised it for being a "great movie".

The 21-year-old was thrilled when Wahlberg invited him to watch the final edit of the movie, in which he acts as executive producer, months ahead of the June release date.

He later revealed that fictional movie agent Ari Gold, played by Jeremy Piven, reminds him of his own manager Scooter Braun, reports femalefirst.co.uk.

"Got to see the #entouragemovie thanks to my friend @mark_wahlberg. Great movie. Thanks buddy. Scooter is Ari. Lol. Everyone go see it," Bieber posted on Twitter on Tuesday.

"Entourage" is a spin-off of the HBO TV series on the same name, which focuses on the career and Los Angeles lifestyle of Hollywood actor Vincent Chase, who is played by Adrian Grenier.

Grenier returns in the lead role for the film along with regular cast members Kevin Connolly, Kevin Dillon, Jerry Ferrara and Piven.

The TV show and movie are loosely based on Wahlberg's experience as an up and coming actor in Hollywood.
