We may not know which male character on 90210 will out himself as gay next season (although all signs point to Teddy) - but we can now confirm the second actor who will be involved in this storyline.

Broadway star Kyle Riabko has been cast as a love interest for the mystery student that finally owns up to his homosexuality on 90210 this fall.

As pictured below, this native of Canada is best known for taking over for Jonathan Groff (Glee) as the male lead in Spring Awakening, the same play Annie co-starred during season one of 90210. Riabko also appeared in the most recent production of Hair.

90210 premieres its third season on Monday, September 13. Take note of the new night and sound off: Are you excited about Riabko's casting?
