Washington, June 19 : Hollywood actress Sienna Miller fears that she''s losing her good looks as she heads towards 30.

The 27-year-old actress believes that it''s time for her to start working out a bit.

"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 any more," Contactmusic quoted her as saying.

"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," she added. (ANI)
