My pretty woman in a ballgown, I'm Richard Gere in a tux
This is a reference to the 1999 movie Runaway Bride in which Julia Roberts (who is the female lead role in Pretty Woman, as well; hence the term’s inclusion) plays the role of a woman afraid of marriage. She has also left a trail of fiances because of it, including Richard Gere (the male lead role in both respective films, too) at one point in the movie…
And if Ocean is Gere, that means that his bride has run away.
