DR. Phil McGraw is making a return to David Letterman’s “Late Show” – seven months after his triumphant first appearance on the show scored big ratings.

McGraw, the host of “Dr. Phil,” will visit “Late Show” on Monday (11:35 p.m./Ch. 2) to shill his new book, “The Ultimate Weight Solution: The 7 Keys to Weight Loss Freedom.”

Letterman has often made fun of McGraw’s aphorisms with his “Dr. Phil’s Words of Wisdom” segment.
