Four months later, Trevor Knight is finally ready to call Katy Perry.

The Oklahoma quarterback sent out a long-overdue tweet to his famous admirer on Sunday night, during Perry's Super Bowl halftime performance:

The much-hyped yet still dormant relationship between Perry and Knight began back on Oct. 4, when Perry declared on "College GameDay" she was picking OU over TCU "based on looks."

If you're wondering what happened after "Trevor Knight, call me!" the answer is not much. A few days later, Knight confessed to reporters he had not called Perry because he did not have her number. Valid excuse.

But Knight's ready to get back in the picture. Perhaps he felt threatened by the fact that Perry donned a black No. 49 jersey during a portion of her performance. Maybe he's getting jealous about the fact Russell Wilson does have Katy Perry's number and texts with her. Maybe, in another life, she would be his girl. (Or maybe she's back with John Mayer.)

With the exception of Oklahoma State quarterback J.W. Walsh, Knight's peers in the Big 12 have been less than supportive of his chances with Perry.
