Some women work out to nab a man. But Beyoncé stays in shape because of her Oscar dream—and her need to wear skinny jeans.

Jay-Z’s wifey showed her helping hand and a superhot bod at Hamburger Helper’s hunger relief initiative at Madison Square Garden.

The black-and-white palette was right in tune with her new music video and we like the natural curls way better than the severely straight hair she sported in her charity commercial. Here’s how you can get B’s dangerously lovely look for under 65 bucks!

Beyoncé’s dream of winning an Oscar helps keep her in shape.

She actually has a painting in her gym featuring the iconic gold statuette so she can run toward her goal. “I look at it, and I’m like, OK, I have to stay in shape,” she explains in the new issue of Self magazine.

That’s not her only motivator…

Shopping also comes in handy. “I buy something too small and then say, ‘I have a reason,’” the 27-year-old singer says. “I need to wear these jeans or this hot dress.”

And then there are the tiny Thierry Mugler costumes she’s been squeezing into for her tour. “[All it takes is to] do a fitting and see that my costume doesn’t fit anymore,” Beyoncé says. “I know I have to keep things in all the right places.”

Who wants to BET that “Single Ladies” wins for Video of the Year?

That catchy tune is just one of the reasons Beyoncé was nominated for a leading five honors at the upcoming 2009 BET Awards, a mark matched only by T.I., who might not be able to make it to the June 28 ceremony his year.

In addition to two nods for top video (the other coming for “If I Were a Boy”), Beyoncé is up for Female R&B Artist of the Year (in which she competes against Jennifer Hudson, among others), Best Actress and a Viewers’ Choice honor.

T.I., who on March 27 was sentenced to 366 days in prison on a weapons charge and is expected to turn himself May 19, shares nominations for Video of the Year and Best Collaboration with Rihanna (”Live Your Life”). He’s also up for Best Collaboration with Yung Dro and Young LA on “Ain’t I,” Best Male Hip-Hop Artist and Viewers’ Choice.

Keri Hilson, Lil Wayne and T-Pain also had strong showings, with four nods apiece. T-Pain will square off against Jamie Foxx, Ne-Yo, Ryan Leslie and the Dream for Best Male R&B Artist. Lil Wayne is up against T.I., Kanye West, Young Jeezy and Rick Ross in the Male Hip-Hop Artist category.

Jamie Foxx, also a multiple award nominee, will host the event at Los Angeles’ Shrine Auditorium.
