Sienna Miller has taken up yoga to help with her pregnancy
The `Factory Girl` actress is currently expecting her first child with fiancй Tom Sturridge and has recently begun practicing the relaxation and strengthening technique because she hates working out.
She said: "I have been trying to do some pregnancyyoga as I`m definitely not a gym person.
"My mum started up one of the first yoga schools in London in the 70s, so I should probably utilise her expertise as I have really bad posture. But I think I`d probably kill her if she tried to tell me to sit up straight."
Sienna thinks her skin looks much better since she got pregnant - though she is unsure whether that is due to her having quit smoking and drinking alcohol.
She added to Marie Claire magazine: "My skin definitely looks better since I became pregnant - although not smoking or drinking has probably helpedwith that.
"Body-wise I`ve been slathering on Dr. Hauschka Blackthorn Body Oil to try to prevent stretch marks, which is gorgeous and certainly seems to have worked so far."
