Sean Penn and Charlize Theron were caught showing a bit of P.D.A. at the Help Haiti Home gala Saturday, Jan. 12, in Beverly Hills, where Penn hinted Theron had inspired him to get rid of his guns.

Penn And Theron Step Out At The J/P HRO Gala

Rumors of a romance between Penn and Theron have been in full swing since the twosome was spotted vacationing together in Hawaii over the holidays. Following their Hawaiian vacation, Penn and Theron were spotted leaving Theron’s home in California the morning of Tuesday, Jan. 2.

Many were skeptical about the initial reports of a romance as the two actors have been friends for years and were rumored to have been dating in 2010 following Penn’s separation from Robin Wright and Theron’s breakup with Stuart Townsend.

Now, it seems Theron and Penn are definitely on. Penn and Theron sat side by side at the event benefiting the J/P HRO, the nonprofit founded by Penn in 2010. Theron cuddled up to her rumored beau and the two reportedly shared a kiss during the event.

“They are spending night after night together and moving very fast. It seems like it’s getting serious and that they can’t get enough of each other,” a source told E! News about the romance.

This news comes just as Penn’s ex-wife, Wright, announced her engagement to actor Ben Foster. Wright and Foster made a similarly P.D.A. filled appearance at the Golden Globes on Sunday.

Penn Hints Theron Inspired Him To Get Rid Of Gun Collection

Some might see Penn’s decision to get rid of his gun collection as proof of his relationship with Theron. At the gala event, Penn contributed a sculpture to be created by artist Jeff Koons – out of Penn’s 60 plus guns – to the silent auction. In presenting his contribution, Penn credited “a strong woman who happens to be from South Africa” for inspiring him to get rid of his firearms. Theron, of course, is from South Africa.

“Being provoked by this aforementioned strong woman and considering how liberating of bulls—t and ugliness it would be not only get rid of the guns I have in the continental United States but also destroy them, Jeff Koons and I had a chat the other day…The highest bidder gets every single one of my guns put in the hands of this iconic artist and sculptor…Koons will decommission [and] render inactive all of my cowardly killing machines,” Penn told the attendees of the piece.

It has been very meaningful to work with @SeanPenn on his @jphro Haiti benefit. https://t.co/IoummEuR7n

The sculpture of Penn’s guns inspired a bidding war between CNN anchors Anderson Cooper and Piers Morgan. Cooper was victorious with his bid of $1.4 million.

Love that @andersoncooper & @piersmorgan just had a $1M+ bidding war for a custom Jeff Koons feat Sean Penn to benefit @JPHRO Haiti relief

The gala raised $6 million for Penn’s foundation, and closed with a surprise performance by U2.
