Sasha Fierce is at it again.

Beyoncé is vamping it up in two new Fall 2010 campaigns for her House of Deréon and Deréon lines, according to a Beyond Productions press release.

For the House of Deréon shots, which were styled by her mother (and creative director/designer) Tina Knowles, the pop star rocks a retro Vargas girl-inspired 'do while channeling a '40s screen siren for photographer Tony Duran.

Modeling a sweeping printed strapless gown (foxy!) and a one-shoulder cocktail dress paired with green booties, Beyoncé poses against a sultry red wallpapered backdrop.

But the singer ditches the Old Hollywood bombshell look in the edgier Deréon ads, also shot by Duran.

Themed "1960s Pinup Girl Meets Futuristic Biker Chick," Beyoncé gets all "Mad Max" on us in a wild blonde beehive, heavily lined eyes, and dramatic temporary tattoos.

And while the other campaign was vibrant and old-school glam, the Deréon shots are sexy, modern, and slick -- with a black minidress-clad, inked-up Beyoncé straddling a motorcycle, flashing a garter, and rocking some seriously hot biker boots.

"These two campaigns feature Beyoncé, but that is where the similarity ends," Tina Knowles says in a press statement.

"They are so different in mood and creative direction reflecting the distinction between the two brands.

"Beyoncé and I love the process of developing the direction for the campaigns and working on the shoots.

"I truly believe this is some of our most memorable work to date, and I am so excited for the public to see and react to them."

Well, we give it two thumbs up... and we're pretty sure that lucky bastard Jay-Z does too.
