Is that a message to the media?

Shauna Sexton was out running errands yesterday, and the Playboy model was wearing a "BS" t-shirt with the full phrase written out on the back. Perhaps she caught wind of the recent rumors going around and this was her response?

According to a new Life & Style report, Jen Garner has issued her ex an ultimatum to break things off with the pinup or face the consequences.

"Jen totally lost it when she found out. She told him to dump Shauna or else. It isn't healthy. It's like whatever Jen says goes in one ear and out the other. She's furious," a source dished to the mag, noting that the actress thinks the 22-year-old is a bad influence.

It sounds like Batman isn't listening to anyone's advice, though.

"He has been told to hold off on a relationship... but isn’t heeding that advice. His closest friends hoped he was just dating her and would break it off after going to rehab, but he seems to get closer to her every day. The more time Ben seems to spend with Shauna, the more he seems to want to go home," another source told ET.

An insider tells X17:
    "Shauna is desperate to keep it going. She's obviously starstruck by him, and thinks he's the sexiest guy ever. Ben has been reassuring her about his feelings via texts from rehab, so she's optimistic that it's more than a fling. Ben's camp would rather he be single and focus on his sobriety, but nobody can tell him what to do when it comes to Shauna. It's more lust than love on his end, but he doesn't want to stop seeing her."

This has already lasted longer than we thought it would!
