Sean Penn and Scarlett Johansson have tried to keep their rumored romance quiet, but it’s all been coming out of late.
 
They were spotted as dates for Reece Witherspoon’s wedding and now they have made quite a stir with a very public display of affection at the annual White House Correspondents Dinner last weekend.
 
A witness at the ceremony commented, “She [Johansson] plopped down in his lap, and they were kissing. It happened right as the main course of the dinner was being put on the table.”
 
The couple separated, but later reconvened at the Vanity Fair after-party where a witness said, “Around 1AM Sean showed up and he and Scarlett were immediately side by side for the rest of the night…They then grabbed hands and walked out before 3AM.”
 
Looks like the romance is heating up!
