Sienna Miller steps out sans engagement ring

The rumor mill was certainly churning last week when Sienna Miller was spotted wearing an engagement ring in London, according to E! Online. However, the British actress recently stepped out in New York City looking fabulous, but was without the engagement ring.

Miller was glowing, as her form-fitting black dress showed off her growing baby bump. The actress is expecting her first child with boyfriend Tom Sturridge. The actress paired the look with bronze bangles and a necklace. She completed the ensemble with her hair slicked back and a bronze clutch.

She stepped out for the Solve Sundsbo fashion video exhibit, which was hosted by W and P&G Prestiage in New York City this past Tuesday. Even though it was Valentine's, she attended the event solo.

According to People Magazine, even though rumors have been flying that Miller and Sturridge are planning a wedding, the couple has yet to confirm their status as a couple. They also haven't officially confirmed that they are expecting - however, it was made quite clear Tuesday night.
