Last night Megan Fox and on-again/off-again boyfriend Brian Austin Green got dinner at the Japanese BBQ restaurant Gyu Kaku in Hollywood, and it sure seems like these two are back on!

Remember when Megan told reporters last week that she was single? Why the public dinner, guys? Maybe this is Brian's way of marking his territory via the media?

Yesterday Christina Aguilera and her son Max stopped by Color Me Mine in Studio City, and it looks like the pop diva had some serious paint on her face! No, we're not talking about her makeup! Look closely and you'll see a little stain on her cheek. Awwww, who knew Xtina was such a hands on mother?

Looks like that time Miley Cyrus and Liam Hemsworth spent together the other day paid off - when we snapped the two on set yesterday, they didn't look awkward at all! In fact, they looked downright comfortable kissing each other!

We also spotted Miley's mom Tish on The Last Song set, and while we're sure she's keeping a very good eye on her 16-year-old daughter, we can't help but wonder if there's going to be more than just onscreen kissing going on in Savannah, Georgia this summer!

We know they supposedly broke up on Monday night, so naturally we were surprised when we saw Lindsay making a booty call at Samantha's on Wednesday night (well, 4am Thursday morning, to be exact).

We were even more shocked to catch Linds leaving Sam's pad on Thursday in a good mood! Of course, Linds looked pretty exhausted too ... so what were these two doing last night? And what's in store for the future?

And since when did Lindsay roll around town in her friends VW Bug? This is a bit of a downgrade from that Maserati and Rolls, right?

But she always looks a little melancholy, doesn't she? Don't get me wrong, I'm sure she's a bit overwhelmed by all the attention she's been getting lately, but she's on her way to becoming a huge star! Maybe she just found out about Rob getting nailed by a cab earlier today? Hey, we were almost in tears too...good thing he's okay!

I bet I know what would cheer her up...

Aww, not only is Rihanna a gorgeous and talented superstar, but she's supersweet to boot! We snapped the R&B songstress in NYC earlier today, and while most people probably wouldn't have had the balls to approach Ri, one determined fan asked her to sign a picture, to which she happily obliged.

P.S. Forget our earlier post about Rihanna's fug boots...we give this outfit (and her slightly different 'do) a 10! From the silver toenail polish to the eyeliner that matches her slinky blue dress, we're in fashion heaven!

Shannen Doherty - AKA Brenda Walsh - is so ridiculously amazing I can't even take it. If you're a messed up Hollywood starlet, just follow this Queen B around for one day and she'll straighten you out. Shannen's been through it all and came out on top!

Plus, check out that bangin' bod. Kelly Taylor is sooo jealous.

Reality TV star slash socialite Kim Kardashian was running errands in the BH earlier today and just one word comes to mind: Juicy!

Kim K. seriously has a fabulous physique - we just can't get enough of it!
