There are 180 days left in 2009, and as such the Fourth of July is the perfect day to celebrate the most shocking Celebrity Love reports of the year to date (or in some cases, not to date). Click on the links to get the full story on these firecracker romantic twists, many of which have occurred in the last couple weeks. They're not duds, no, no. In fact, they set the celeb world ablaze.

Michelle Obama Baby Buzz Everyone's favorite First Lady Obama wowed us with her Inauguration Day style in January...and then almost gave us a heart attack when we heard she was preggers by Valentine's Day. (Hey Mr. President: there's celebrating, and then there's doing the nasty on a seamless.) Observers wondered whether her notorious Inaug wardrobe left a little room for a bump, but alas, we were hallucinating.

Britney and Justin's Two-Time Run-Ins Is it weird that there's still a little piece of us that hopes these two will get back together? First they both performed at a Madonna concert last November (reports said there was no interfacing backstage), then earlier this year they crossed paths at a West Hollywood eatery, where Jessica Biel accompanied Justin and Britney reportedly, well, didn't look so hot. We heard last week that she's engaged to her manager, but hey, there's always August through December to keep our fingers crossed.

Jennifer's Oscar Feat In Front Of Brangelina Whew. We were all watching and not breathing. But even with ex-husband Brad Pitt and femme fatale he-left-you-for-me Angelina Jolie looking on, Jennifer Aniston delivered a typically lovable, lovely and impossibly composed speech to present the award for best animated film at the Oscars. We weren't surprised to hear that Jen and Angelina exchanged a secret smile—pure class. You know we're fans, Jen. Go girl.
