The L.O.L. Surprise! O.M.G. (Outrageous Millennial Girls) are fashion dolls that are the bigger siblings to popular/fan favorite L.O.L. Surprise! tots and lil sisters. It is the third overall spinoff to the LOL Surprise line, succeeding the L.O.L. Surprise! Pets and L.O.L. Surprise! Lils.
The dolls debuted on July 7th 2019, with the first line (Series 1) featuring Royal Bee (big sister to Queen Bee), Neonlicious (big sister to Neon Q.T.), Swag (big sister to M.C. Swag), and Lady Diva (big sister to Diva).
Since then, many lines have been released and a total of 70+ characters have made their debut in the line including the first ever OMG boy, Rocker Boi, who was exclusive to a two-pack with Punk Grrrl in 2020.
In Late August 2021, the first animated series entitled “L.O.L. Surprise House of Surprises” premiered on YouTube. The series revolved around Royal Bee, Neonlicious, Swag, and Lady Diva as they were discovering the life and times of the House of Surprises.
