Enjoying a fun-filled evening in London, Sienna Miller was spotted leaving the Hoping’s Got Talent shindig in the West End last night (June 18).

The “Factory Girl” hottie looked lovely in a black blazer, slim-fit jeans, and grey platform heels as she made her exit from the Café De Paris.

In related news, Miss Miller recently confessed that she’s beginning to worry that her fine form may begin to decline as she gets on in years.

Sienna told press, “I'm lucky I've got a good metabolism. I'm very grateful for that. But I'm not toned at all. I think I've reached an age at 27 where it's time for me to start working out a bit. I can't get away with it anymore.”

She added, "I used to be quite firm and tiny and, as I hit 25, things started to change. Now I'm 27 I'm noticing more changes - bare legs at the top and back is not a pretty sight. I'm lazy and if I wear clothes, it's hidden well. I don't feel like a beauty icon. I get pretty insecure and have the same insecurities as everyone else - sometimes more because there is more focus put on me."
