Olivia Wilde
looks ready to pop! 

The actress showed off her growing baby bump at the 2014 Revlon Concert for the Rainforest in New York on Thursday. 

Sporting a sheer, long-sleeved, black maxi dress, the brunette beauty looked gorgeous for her charity appearance. Wilde is also the brand ambassador for the popular cosmetics company.

The 30-year-old announced that she and fiance Jason Sudeikis were expecting their first child together, a baby boy, last October. 

The cute couple, who first started dating shortly after they met on the set of "Saturday Night Live" back in 2011, got engaged in January.
