Sienna Miller, who is pregnant with her first child, debuted her baby bump publicly at the recent unveiling of "The Ever Changing Face of Beauty" video installation, created by fashion photographer Solve Sundsbo at the Park Avenue Armory in New York.
The event took place on Tuesday - Valentine's Day - and was hosted by hosted by W magazine's editor in chief, Stefano Tonchi. Miller, 30, wore a black, halter-style Boss Black gown, Pamela Love gold jewelry and her hair swept up and pulled back in a bun. The British actress is a spokesmodel for Boss Orange, a fragrance by Hugo Boss.
The event was also attended by celebrities such as Cate Blanchett, who arrived in a Juan Carlos Obando black chiffon gown with white, mint and silver tones and gold Christian Louboutin peeptoe heels, and Evan Rachel Wood. (See photos of Sienna Miller and others at the unveiling here.)
The "True Blood" and "Mildred Pierce" actress donned a strapless, grey, plaid Gucci knee-length, belted dress and black sandals and posed with "Captain America" star Chris Evans. The two starred in a sexy ad campaign for the Gucci Guilty Intense fragrance last year.
Miller's pregnancy was first reported in January. Us Weekly magazine said she and her boyfriend, "Pirate Radio" actor Tom Sturridge, told friends over the Christmas holiday about their expected new arrival. The two declined to comment about the matter or about the status of their relationship. People magazine said Miller is due to give birth in the summer.
Miller and Sturridge, 26, have been dating for about a year. Sturridge made his big-screen debut opposite Reese Witherspoon in the 2004 film "Vanity Fair." He has since starred in films like "Being Julia," "Like Minds," "Pirate Radio" and "Waiting for Forever."
He will next appear as Carlo Marx in "On The Road" opposite Kristen Stewart, Garrett Hedlund, Kirsten Dunst and Sam Riley, as well as "Effie" as the love interest of Dakota Fanning's character, Effie Gray.
Miller has starred in movies such as "G.I. Joe: The Rise of Cobra," "Factory Girl" and "Alfie," where she met her on-and-off boyfriend "Sherlock Holmes" actor Jude Law.
Law and Miller were engaged in December 2004. In mid-2005, the actor was reported to have had an affair with Daisy Wright, the nanny of his three children, whose mother is Sadie Frost. Law made a public apology, saying he was "deeply ashamed and upset" that he hurt Miller and their families.
The two soon broke up months later and got back together in 2006. The actress said the two were trying to work things out. They then split again and Miller reportedly dated actors such as Rhys Ifans and later, Balthazar Getty, who was married at the time. She and Law rekindled their romance in 2009 and broke up in early 2011.
