Robin Thicke wants that old thing back. The R&B crooner pleads with his wife of nine years, Paula Patton, on “Get Her Back,” which he debuted at last night’s Billboard Music Awards. On the touching dedication, which he wrote following their separation, he promises to do right this time.

“I should’ve kissed you longer / I should’ve held you stronger / And I’ll wait for forever for you to love me again,” he sings to the mother of his four-year-old son Julian.

The high school sweethearts announced their split in February. Thicke has been trying for months to win back his wife, even dedicating “Lost Without U” to her at his recent shows.

Hear him shout it from the rooftops.
