Robin Thicke has written a song about his desperate desire to reunite with estranged wife Paula Patton, and he will debut that tune live at this weekend's Billboard Awards. TMZ is reporting the song is called "Get Her Back," and contains lyrics like, "All I wanna do is make it right," "I gotta treat her right, I gotta cherish her for life," and "I should've kissed you longer, I should've held you stronger."
