And they all followed Timberlake while he browsed... his own line of clothes. It seemed every floor began playing Justin Timberlake right at this moment. Source: www.esquire.com

Scans of Anne Hathaway and Jake Gyllenhaal for Entertainment Weekly: Session #7

"Jake Gyllenhaal was advised to repeat the mantra “I am not Justin Timberlake” while he was shooting his new movie Love & Other Drugs.

Jake’s co-star Oliver Platt has revealed he urged the Hollywood hunk to regularly chant the phrase to himself in order to get into the role. Both Jake and Oliver insist it is not an insult to the successful singer-and-actor, rather it should be taken as a compliment.

“It was a little joke between us on the set, there's no scandal", Oliver told the New York Post.
Anne Hathaway, drector Ed Zwick, actor Oliver Platt and actor Jake Gyllenhaal attend a screening of "Love & Other Drugs" at DGA Theater on November 16, 2010 in New York City.

The pair attended a screening of Love & Other Drugs on Tuesday night and Oliver wasted no time in reminding Jake of his words of advice. After they had watched the movie, he approached Jake and whispered the mantra into his ear, before lifting up his arms and shouting it to his friends at Rouge Tomate restaurant in New York.
While some onlookers believed Oliver was poking fun at singers who try their hand at acting, Jake and Oliver are adamant it is a reminder that they are not as talented as other stars.Justin Timberlake and Jesse Eisenberg as Sean Parker and Mark Zuckerberg in "The Social Network" (2010)Justin Timberlake, Andrew Garfield and Jesse Eisenberg pose for photos together at the presentation of their new film "The Social Network" in Madrid on October 6, 2010

"Oli and Jake are huge Justin Timberlake fans, especially from the SNL videos he does,” a representative for the pair said. “Oliver just met him at The Social Network premiere. The joke is that he can sell millions of records, sing, dance and do everything. He meant Jake is a really good actor, but he's no Justin Timberlake." Source: unrealityshout.com
