It's by Josh Duboff, and it's a series of short vignettes featuring the reactions of Gwyneth Paltrow's exes to her recent break-up (including one where Chris Martin finds 11 txt messages from Lindsay Lohan on his phone).

Ben Affleck comes in from the garage to find Jennifer Garner baking a cake.
"What are you doing?" he asks.
"Oh," Jen says, cheerily, "I'm sending this to Gwyneth."
"You've like . . . only met her twice."
"I know, but that doesn't mean I don't feel for her, and want to express my sympathies."
Ben frowns slightly and sits down at the counter. "You know she's not gonna eat that, right? There's gluten in it."
"It's the thought, Ben."
"Do you see me sending flowers to all of your exes?"
"Go right ahead, sweetheart," Jen says, looking up at him. "You might be surprised at how good doing that would make you feel."
Ben stands up and heads to his office. "Well, while you're at it, why don't you send J. Lo a fruit basket just for the hell of it?!"
"Not a bad idea," Jen whispers to herself.
