Emma looks so beautiful! :)

I like the dress. She's been trying a lot of different things during the 'Perks' promotion. :D

Bonnie was at the LA premiere too. Ahh. HP love :D I miss the cast and the HP premieres. :)

Emma's beautiful as always and Bonnie too. FINALLY! :)

A shame they don't have a picture together. They both look great though!

Both look beautiful!

Yay! Bonnie is such a supporter! totally Emma's night and Bonnie is there for her! Well done! I am loving it! Hey, did Bonnie, Emma and Daniel all meet up later? Hmmmmm. Curious minds would love to know.

Go Bonnie!

I wish they would have taken a picture together all, but still...lovely!

Emma looked stunning at all the premieres...especially Toronto one...how cool is it that Bonnie supported Emma...it is too bad there were no pics...Bonnie was tweeting that she was in CA for the last 2 weeks so it was cool she made it to LA to cheer on Emma.

Support is great :)
