Christina Applegate outside the Ed Sullivan Theater for 'The Late Show with David Letterman'. New York City, USA - 23.03.09

The odd couple became email pals after meeting on the set of video skit I'm F**king Ben Affleck - and spent weeks texting each other, but then Jett stopped replying.

The Anchorman star says, "She was so awesome... and she and I became email buddies for quite a while - for, like, a few months.

"I haven't heard from her... I think she just got busy. She sent me a box of shirts and sweat shirts and stuff and that was kinda it.

"She was cool, she's a really cool lady."
