Serena Williams is all about Justin Bieber on the Ellen DeGeneres Show.

Serena Williams ,35, revealed her Bieber fever as she played "Who'd You Rather" on the Ellen DeGeneres Show on Friday. Nov 18.

DeGeneres assumed that Williams has no one special in her life, in which the tennis star replied, "Well, I didn't say that." To this response, the host decided to change her question.  She asked the tennis star if she does have anyone special in her life. The tennis star decided to remain aloof, replying "I didn't say that either."

Since Williams has so many "sexy SnapChats," DeGeneres thought she had to have someone special. She then decided the best way to get this out of her is to play a game called "Who'd You Rather," throwing a bunch of hunks her way.

When asked who would she would rather, between Idris Elba and Justin Bieber, Williams began to laugh and asked, "What Do You Mean?" It turned out that her choice was between Idris Elba and Bieber.  Her choice was "definitely" Bieber. The tennis star stated her claim as she pumps her fist into the air. As the game continued, Williams stayed on Bieber.

When DeGeneres questioned her choice, Williams shared, "You know what, it's always gonna be Justin Bieber."
