BOW WOW PISSES OFF CO-STAR ON SET!

Funnyman BRANDON T. JACKSON struggled to film his most dramatic scenes with BOW WOW for upcoming comedy LOTTERY TICKET - because the rapper was constantly tweeting fans in between takes.The Tropic Thunder comedian was eager to impress fans with his dramatic acting skills in the new role. But the Girlfriend hitmaker-turned-actor made it hard for Jackson to re main in character - because the set was flooded with Bow Wow's fans as so on as the rapper posted updates about his whereabouts on social networking website Twitter.com.

Jackson says, "He likes to tweet on set. I'm trying to be in the scene, I'm trying to be a good actor. And Bow Wow's a good actor, I love Bow Wow, but we've got this dramatic scene... and he's tweeting. I'm trying to get my Denzel (Washington) on. I'm trying to get my facial expressions, and then he's just tweeting and next thing you know there's like girls on the set and I'm like, 'Are we shooting a music video or a movie?'"
