Megan Fox surprised fans by making a special appearance Monday at the VH1 Do Something Awards in Los Angeles.
She also provided a glimpse of her sparkling wedding bling from new husband Brian Austin Green.
Details of the ring remain unclear.
Us Weekly first reported that Fox, 24, lost a 2-carat engagement ring on a Hawaiian beach just hours after Green, 26, proposed June 1.
The two went on to wed in a hush-hush ceremony June 24 in Hawaii. See Miranda Kerr's romance tips.
