MEGA STAR JAMIE FOXX outdone by Magic Mike stud monkey costar and he’s NOT happy – sources.

 OSCAR winner Jamie Foxx is being eclipsed by his “White House Down” co-star Channing Tatum, and sources say he’s not happy!

The two actors have worked nonstop to promote the film, but Foxx has played second fiddle to rising star Tatum, who’s been deluged with questions about his skyrocketing career and new baby girl.

“Fans at the premiere in Washington, D.C., were practically shoving Jamie out of the way to get a picture with Channing,” a source told The ENQUIRER.

“Jamie isn’t used to that. He’s usually the star of the show wherever he goes.

“And the questions that reporters asked Jamie most frequently were, ‘What’s it like to work with Channing?’ or ‘Have you seen Channing’s new baby yet?’

“It’s made Jamie feel like chopped liver!”

Foxx, 45, has built a stellar film career, highlighted by his Best Actor Oscar for “Ray,” the 2004 biopic of the legendary Ray Charles.

BUT Tatum, 33, isS Hollywood’s hottest young star, scoring three top box-office films in a row with “21 Jump Street,” “The Vow” and “Magic Mike.” The former model married his “Step Up” co-star Jenna Dewan in July 2009, and on May 31 she gave birth to their first child, daughter Everly.

“The baby was conceived while Channing and Jamie were shooting ‘White House Down,’” another source noted.

“Her birth put a whole new spin on promoting

 the movie. It all became about Channing being a first-time dad, and it was unfortunate timing in Jamie’s mind.”

To make matters worse, in contrast to Channing, Jamie believes in keeping his private life out of the spotlight, said the source.

“Channing will talk to anyone about anything at any time,” said the source.

“Producers love him because that helps sell movies, but actors like Jamie think it’s grandstanding.

“Still, Jamie says while Channing may be hunk of the month, he’s the one with an Oscar on his mantle!”
