Courtenay Semel seems to be turning back to men after the death of her lesbian love, Casey Johnson. The daughter of ex-Yahoo CEO Terry Semel was seen making out with Alex Quinn at the Crown Bar in LA Sunday night. Quinn — who briefly dated Semel in 2005 on the E! reality show “Filthy Rich: Cattle Drive” — confirmed they kissed. He told us, “I love Courtenay, and I am helping her through this difficult time. I am really attracted to her, and who knows what will happen?” But a friend of Courtenay’s said, “While she and Alex are close, she’s still in love with Casey and isn’t ready to date anyone seriously.”
