Could Sean Penn and Scarlett Johansson be more than food companions? It seems like they could be semi-serious—by Hollywood standards, that is.

The duo took a trip down south—and we don't mean Scarlett's traveling foot—to have dinner in Mexico recently, and we've just been informed S Squared have booked another getaway together...

Sources say that Penn, 50, and Johansson, 26, are planning a trip to Haiti together for later this spring.

Johansson, who campaigned for Obama and serves as a global ambassador for Oxfam, is working with Penn on his ongoing relief efforts in the devastated nation.

Guess sometimes those two really do talk politics!

Remember, we were first assured by ScarJo's rep that the two simply bonded over Haiti (yeah right)...And then we got word the duo really were hooking up, which reps denied.

But now, after their flirty lunch and Mexican getaway, both camps are staying quiet.

Perhaps it's more than just some casual hookups?

While at a pre-Oscar party the other weekend in the Hills, we're told by sources there that Sean was surrounded by beautiful model types all vying for his attention.

And get this: The perpetual flirt didn't look twice!

Wonder if that's because he's super into Scarlett? Both Sean and ScarJo were at the Vanity Fair party after the Oscars, and we're told by sources there they avoided each other like crazy.

That's sign No. 1 that something is up!

Still, don't think Ryan Reynolds is sitting around moping. Yesterday he was seen engaging in some tush grabbing with an unidentified blonde while on location in South Africa.

And you know what we say? Well played Ryan, well played. We all know high-profile romances in H'wood have a shelf life of a few seconds. Think you and your ex have the right rebound ideas!
