Surely, the coming out of 'Prison Break' star Wentworth Miller was a like a big bomb that blasted in the online world. It was not just the fans and regulars netizens who have reacted but moreover, other celebrities who have shown support to Miller.

The 41-year-old actor is not the first in Hollywood who bravely opened up the truth with their sexuality. In fact, there are many others out there who were as courageous to take the big step of admission. Here are some of the most shocking admissions made by popular celebrities:

Frank Ocean. It was just last summer when he made the revelation of him being a bisexual via a poetic Tumblr posting saying his first love is a guy.

Jason Collins. Who will not forget the famous admission of NBA player Jason Collins through a Sports Illustrated cover story? He is the first ever active professional athlete to have come out of the closet as gay.

Ellen Degeneres. The tv host' decision to come out came way back in 1997. She was bombarded with criticism but managed to rise above it all. Now she is married to Portia De Rossi and has her own daytime hit show, "The Ellen Show."

Neil Patrick Harris. Known to be America's Dougie Howser M.D., he came out in 2006 and still won the hearts of fans with his role in 'How I Met Your Mother.'

Ricky Martin. After years of silence, the hit and hot singer came out not just with his real self but with lovely twins and the launch of his tell-all book.

Other celebrities who came out recently include Matt Bomer, Jim Parsons and even Zachary Quinto. Other names in the industry who are still dealing with rumours of being hidden in the closet include Jamie Foxx, Queen Latifah, Ellen Page, John Travolta, and even Tom Cruise!
