Emma Watson has updated her Official Site with a new note.

There are a few new faces around set, such as Jessie, who plays the character Lavender, who is really cool, although our characters really don’t get on in the film! We have actually just finished filming a scene with Lavender and Ron kissing, where Hermione gets really jealous which was quite fun!
Only a few days to go now until Christmas, I’m so looking forward to seeing all the family and having some quiet time! I hope you all have a wonderful Christmas and I will update you with all the news in the New Year!

Thanks Laura and JessieCave.com!
