Miley and Justin's Postinaugural Dinner Date

Teen singer Cyrus steps out for a sushi date with her man...find out who paid!

Just back from performing at the inauguration, Miley Cyrus wasted no time hitting a Hollywood hot spot with Justin Gaston.

Last night, the two lovebirds dined on sushi at Koi, wearing matching black leather jackets.

“They seemed like they were having a great time over dinner and were polite and friendly to everyone around them,” says a source.

And why wouldn't they be? Miley told paps afterwards that she and Justin didn't pay a dime for the pricey dinner.

"We're cheap!" she told photogs as she explained why they didn't valet. When one pointed out that Koi wasn't cheap, Miley explained that it was a free dinner.

"We didn't pay," she added. "We have friends! That's the best, isn't it? When the check comes and you pretend like you didn't know they got it."

Maybe the economic recession is hitting the Disney starlet?
