Keira Knightley

Keira Knightley showed off her new wedding ring when she hit the nightlife scene in London yesterday after wrapping up her honeymoon with her new husband, James Righton, in Corsica, France, earlier this week. She flashed her jewellery when she left the Groucho Club late last night and caught a cab home. Keira got married in the South of France on May 4, and she chose an understated yet decidedly different wedding band to symbolise her union with her rock star love. While her engagement ring reportedly featured a platinum band and a two-carat solitaire diamond, she apparently went for a simple yellow gold wedding band. We got a glimpse of her ring when Keira wore a bikini during her honeymoon, but now we can finally see the stylish star's jewellery up close.

Keira isn't the only elegant British celebrity who mixed metals for her wedding jewellery — Kate Middleton's engagement bauble featured a sapphire set on a platinum band, but her wedding ring was a simple yellow gold band.

This week's casting news is fun, with Game of Thrones star Richard Madden (better known as Robb Stark) signing on for Disney's live-action Cinderella, Jessica Alba boarding an indie romantic comedy, and Andrew Garfield signing on for a Martin Scorsese film.

We're inducting Katy Perry into our floral crown hall of fame, following her appearance at a photocall for The Smurfs 2 at the 5th Annual Summer of Sony party overnight. Floral crowns are always a hit on the red carpet, at the races (we're looking at you Delta Goodrem!), premieres and more, and we can totally see why — they look incredible. Flower headpieces are so pretty, so feminine, so colourful and best of all, so easy to whip up. While you could buy a professionally-made crown at a florist, it's super simple to craft your own. All you need is fishing wire and a couple bunches of your fave flowers — the fuller the better. Thread the flower buds and blooms onto the wire (being sure to include a few bits of greenery, too), then close the fishing wire to make a circle large enough to sit atop your head. Lock it in place with some discreet bobby pins, and voilà! Fit for a pretty princess. Click through the gallery for some celebrity inspiration!

Keira Knightley has built her reputation as the leading lady of our favourite period pieces, like Pride and Prejudice, Anna Karenina, and Atonement — but her red carpet résumé could easily rival her on-screen costumes. With a penchant for beautifully crafted, ultrafeminine wares from Valentino, Chanel, and Elie Saab, Knightley might just have one of the loveliest red carpet histories in Hollywood (and she's only 28!). In honour of the very talented — and totally gorgeous — actress's birthday yesterday, we're celebrating with a look at her best red carpet moments thus far. Keep clicking to see her top 11 looks.

With the wave of celebrity betrothals last year and this year (already!), it looks like we've got a lot of weddings to look forward to soon. Jennifer Aniston was one of the biggest names (and most hotly-anticipated) to confirm an engagement, and the huge ring that Justin Theroux presented to her made his feelings very clear indeed. Olivia Wilde and Jason Sudeikis announced their engagement in January of this year, and her ring is one of the most unique we've seen. We also did some drool-inducing research so you can check out the best rocks around, from Princess Grace of Monaco to the Victoria's Secret angels, plus Aussies Miranda Kerr, Rachael Finch and Jen Hawkins. And if the man in your life needs a subtle nudge (or kick) in the right direction, why not pass the link on . . .
