On Thursday -- the same day she announced her engagement to Us Weekly -- Amy Smart rocked her brand-new rock from fiance Carter Oosterhouse at an Earth Day event hosted by the Body Shop in NYC.

The Just Friends actress, 35, wore a huge new engagement ring from the HGTV hunk, 34, at the Earth Lovers in Celebration of Earth Day event. She admitted to Us that Oosterhouse wasn't her "boyfriend" anymore -- but her "fiance!"

She added that the engagement was "very new" and "very exciting." One insider revealed to Us that the engagement went down earlier this week in L.A..

The eco-conscious pair met at a green charity event in November. "They are perfect for each other," another source told Us. "Here are two wholesome, kind, sweet Midwestern types. Neither has sold out and gone Hollywood."
