Pregnant Sienna Miller Rocks Horizontal Stripes and Skinny Jeans

Sienna Miller’s pregnancy certainly isn’t putting a damper on her style!

The 30-year-old mom-to-be rocked skinny jeans, horizontal stripes and an adorable black shawl today on the streets of London.

But is Tom Sturridge’s ladylove (they’ve yet to officially confirm they’re engaged!) planning to be barefoot and pregnant?

Heck no! Look at those ankle boots. Miller was at work shooting a commercial for Amore Pacific skin care line.

The star recently told Vogue about her pregnancy. “I’m feeling fine,” she said. “It’s all progressing nicely and it’s very exciting.”

We’re certainly excited to meet Sienna and Tom’s little one, who will undoubtedly be a sharp dresser!

Sienna Miller and her baby bump film advert in London

Sienna Miller and her fast-growing baby bump – which seems to be burgeoning at the speed of light – were hard at work filming an advertisement in London yesterday.

The 30-year-old actress was spotted on location in the capital working a number of typically stylish looks as she showed off her expanding stomach.

She looked achingly cool in a striped Breton top, skinny jeans and ankle boots as she worked it for the camera, before changing into a flowing white summer dress.

Miller, who is expecting her first child with boyfriend Tom Sturridge, 26, hasn’t slowed down one bit since becoming pregnant and last month was seen filming scenes for new movie A Case of You in New York.

Although she is refusing to give too much away about her pregnancy and private life in general, she did recently reveal that she’s developed a severe sweet tooth now that she’s a mum-to-be.

‘I feel very grounded, more than ever – it’s a wonderful feeling. But all of a sudden, I’ve started to get cravings,’ she said, explaining she wanted a vanilla ice-cream topping for her brownies.

‘I usually don’t have a sweet tooth but these tarts I could eat all day long!’ she added.
