Beyonce's summer of getting back to business just got more hectic.  She's just been named as one of the lead voices for the upcoming animated film, Epic.  Deets inside, plus the fashion run down on all of her and her dancers' REVEL concert looks, and Blue Ivy's famous new babysitters...

She's already got Clint Eastwood's A Star Is Born leading role in her back pocket, now, Mrs. Knowles Carter has been named as one of the voices for the animated flick Epic.  The 3D CG movie is from the makers of the big budget films Ice Age & Rio.

Beyonce will voice the character Queen Tara, and plenty of other celebs are rounding out the cast: Colin Farrell as Ronin, The Hunger Games‘ Josh Hutcherson as Nod, Amanda Seyfried as Mary Katherine, Johnny Knoxville as Mandrake, Aziz Ansari as Mub, rapper Pitbull as Bufo, Jason Sudeikis as Bomba, and Steven Tyler as Nim Galuu.

According to Deadline:

The film is described as a battle deep in the forest between the forces of good and evil. When a teenaged girl finds herself magically transported into this secret universe, she must band together with a rag-tag team of fun and whimsical characters to save that world, which in turn saves the real world.

Epic will be released May 24, 2013.

And if you were wondering who was looking after almost 5-month-old Baby B.I.C. up in Revel's Penthouse while Mama Bey was downstairs shutting down the stage--it was her Destiny's Child besties Kelly Rowland & Michelle Williams.

TMZ caught up with Michelle last night and they report:

Last night in NYC, Michelle revealed Kelly Rowland also pulled a shift watching B.I. in Beyonce's hotel suite ... during B's concert in Atlantic City last weekend.

In the middle of the show, Beyonce thanked Michelle for babysitting -- but Michelle 'fessed up to us she had some help ... and even got to go downstairs to see some of the show.

Cute!
