“The Bachelor” Jake Pavelka thinks his “On the Wings of Love” series is going to propel him to worldwide fame. He’s hired p.r. firm Rogers & Cowan, which also looks after Sylvester Stallone, John Travolta and Bruce Willis, to rep him. Sources say Pavelka — recently described by ex Tanya Douglas as “fame-obsessed” — wants to turn his new celebrity via “The Bachelor” and “Dancing With the Stars” into an acting career.
