Brad Pitt, 55, is reportedly 'dating' actress Charlize Theron, 43 and they were all over each other last week'

Brad Pitt has reportedly gotten himself another woman two years after he split from his Oscar-winner wife Angelina Jolie.

According to The Sun, the 55-year-old Allied actor is seeing Charlize Theron, 43.

They were introduced by her ex-fiance Sean Penn, it was alleged by the publication.

'The new lovebirds were all over each over at a showbiz function last week,' a source claimed.

The site reported that the function was a showing of the movie Roma at the Chateau Marmont in West Hollywood on January 12. Theron was at the party and Pitt came later after a screening of his movie If Beale Street Could Talk, where he posed with Blanca Blanco.

'Brad came over to Chateau afterwards, changed his outfit and joined Charlize in a corner of the bar,' said the insider.

'She was on a vodka cocktail while he stuck to mineral water,' noted the source.

'They were ridiculously touchy-feely and his arm was around her back. At one point he winked at her,' said the eyewitness.

'Brad seemed in a really good place — they both looked really happy,' added the source.

The power couple started dating around Christmas, it was claimed, and they spend a lot of time at his Los Feliz, California mansion, though it was noted she has yet to meet his kids Zahara, 13, Shiloh, 12, 10-year-olds Vivienne and Knox, Maddox, 16, and Pax, 14.

'They have been casually seeing each other for nearly a month now. They’ve been friends for some time ironically through Sean but things have developed,' said the insider.
