So, George Lucas (he's this filmmaker, maybe you've heard of him? I forget which movies...) is getting married! George Lucas and his girlfriend of seven years, businesswoman Mellody Hobson, are engaged.The famed director, 68, and his longtime partner and president of a big-time Chicago-based investment management firm, Ariel Investments LLC, 43, are no strangers to showcasing their relationship in the spotlight. The pair are often spotted hand-in-hand on the red carpet, everywhere from the Cannes Film Festival to Formula One Grand Prix races to the NAACP awards. This will be the second marriage for the "Star Wars" writer-director -- he was previously married to Marcia Lucas (1969–1983) -- and the first marriage for Hobson, who helms the $3 billion investment firm and is a regular financial contributor to "Good Morning America."Lucas recently made headlines after donating $4 billion to an education foundation -- the amount he received after selling Lucasfilm Ltd. (which Lucas solely owned) to Disney.
