The lead up to the Oscars (the show's on tomorrow!) is always a busy time for celebrities, and it seems like this week has been one of the most hectic yet! Between the Brit Awards on Wednesday night, a few movie premieres and screenings and a lot of pre-Oscars parties, we had a lot to keep up with! Miranda Kerr and her husband Orlando Bloom put an affectionate end to rumours about marriage problems, while another Aussie, Chris Hemsworth, brought his young family to Sydney for a quick work-related trip. Kate Middleton stepped out on royal duty, with a very special bump on board, and Rihanna celebrated her birthday with on-again boyfriend Chris Brown. That's not even close to all that happened this week — click through to see the whole week in pictures!

Rihanna held hands with Chris Brown in Hawaii on Wednesday. She wore a tiny pink bikini with a black fishnet cover-up for a special occasion — it was her 25th birthday. Rihanna was apparently in good spirits, tweeting, "Epic day already, I woke up to sunshine in paradise and 'Stay' jumped 54 spots to number 3 on the Billboard Hot 100!"

Apart from turning 25, Rihanna has big projects to celebrate. Rihanna debuted her first clothing collection for River Island during London Fashion Week. She will also delve into the world of beauty. Rihanna will collaborate with MAC to launch her own line of makeup for the brand, which is due to hit stores later this year.

Rihanna and Chris Brown may have walked the Grammys red carpet separately, but they met up inside the Staples Center once the show got started today. It's been a busy weekend for the duo, who were also together at the Roc Nation pre-Grammys brunch on Saturday. Rihanna and Chris are spending time more together lately, though they have yet to comment on the official status of their relationship. Both Rihanna and Chris are up for awards today, and Rihanna will also take the stage to perform.

Rihanna and Chris Brown cuddled close and shared tons of laughs at the Christmas Day LA Lakers game at the Staples Center on Tuesday. Rihanna sipped on a beer and rested her head on Chris' shoulders as they watched the Lakers win. Rihanna ended her Barbados vacation in time to join Chris courtside for the holiday. Rihanna and Chris have yet to officially state that they are back together, but they have been going more and more public with their rekindled romance. Rihanna has shared a number of pictures of herself and Chris looking intimate on Instagram in recent weeks. Rihanna slipped into a bikini for a getaway to see friends and family earlier in the weekend, but she made sure to be with Chris on Dec. 25.

Wow, what a week! The beginning of September is always heaving with events, the smell of the new season in the air and enough fashion and film festivals to keep us plenty occupied — this time around was no exception. Michelle Obama impressed millions around the world with her inspiring speech, Kristen Stewart finally came out of hiding after her cheating scandal (and she's looking better than ever!) and a certain royal and his almost-royal sister-in-law have been making waves for very different reasons. The fashion set came out to play for Fashion Week's kick-off, and the MTV VMAs were the colourful and happy riot they always are. But, that's not even a fraction of what's happened this week — click through the gallery and catch up on the massive week that was!
