Rob's early success
Born on 17 March 1964, Rob Lowe went on to rule the screen throughout the '80s - cementing his place as an icon of the decade as a core member of the famed Brat Pack. His career credits include beloved features like The Outsiders (1983), St. Elmo's Fire (1985) and Youngblood (1986).
More recently, he's won over a new generation with a five-year role on 9-1-1: Lone Star and hosting duties on game show The Floor.

Justin is father to son Jackson and happily in love with an unnamed partner. Chuck is clearly a doting father and grandfather, sharing photos captioned "Great couple, Jackson’s parents" and "Wonderful grandson, Jackson".
