While most TV hunks lust after barely legal starlets, Robert Buckley has a much more mature taste in women. The Lipstick Jungle actor, who stars as Kim Raver’s boy toy lover in the NBC hit, can’t get enough of veteran actress Helen Mirren, 63. “Have you seen those pictures of her on the beach?” Robert asked In Touch at the Armani Exchange “Kiss for a Cause” event in Santa Monica on February 7. “She is talented and hot!” The 27-year-old clearly couldn’t get enough of the hot shots of the Queen vixen in a red bikini while vacationing in Italy last July. But watch out, Robert — Helen has been married to producer-director Taylor Hackford for 11 years!
