We just caught Beyoncé sporting the most outrageous red lip in her newest commercial for L'Oréal Paris.

The spot takes us behind-the-scenes as Sasha Fierce shares air-kisses, a cup of tea and giggly rehearsal notes with her back-up singers.

It's all so full of glitz, glamour and girl-power, that we're instantly wanting to jump in on the fun.

The classic pin-up red lipstick that Beyonce is wearing is just one of L'Oréal's new star spokesmodel-inspired shade collection of Infallible Never Fail Lipcolour Compacts.

In addition to Beyoncé's red, you can swipe Eva Longoria Parker's Caramel, Diane Keaton's Tuberose, Linda Evangelista's Beige, Andie MacDowell's Rose and Kate del Castillo's Plum.

Each compact comes with both a non-transfer lipstick and a top coat stick made of hydrating marine collagen and vitamin E to seal in color with a dose of high-shine moisture.

The reflective compact doubles as a mirror for application on-the-go, and the brand claims that you can pull up to 16 straight hours of lasting tint on your lips.

We have to admit to playing favorites here -- while all of the shades are pretty and totally wearable, Beyoncé's Red is the true Hollywood standout.

We're so in love with the shade that StyleList has arranged for one reader to receive and try out Beyoncé's Red for free!

Disclosure: We can't be held responsible for hot events that may occur after application.
