Handler has now finally opened up about their romance, telling talk show host Piers Morgan, "We dated - very causally."
She added, "He's a very sweet, nice guy. He's fun, a great guy. He's the complete antithesis of what you would imagine. Sweet, funny, a great sense of humour."
Handler also used her appearance on Piers Morgan Tonight to address rumours her new boyfriend is Uma Thurman's former lover, hotelier Andre Balazs.
She told the host, "I'm seeing someone now. I feel like I talk about my love life (too much)."
When asked by Morgan, "Is he a hotelier?", she replied, "That sounds familiar actually! I have spent so much time exposing my personal life to everybody that I'm finally in a situation where I feel like it's disrespectful to another person.
"We all know who I'm dating! What do you want me to talk about? Underwear?! Sorry, I'm not being coy, we all know what's happening. I've learned to respect somebody else's privacy. He has children, so I have to be nice."
