AKM-GSIWell, don't they all look adorable together?!
Sean Penn and girlfriend Charlize Theron were snapped on the beach together in Malibu, Calif., where the loved up couple was spotted taking a romantic sunset stroll with the Snow White and the Huntsman star's son Jackson in tow.
The Oscar winners were unafraid to flaunt their affection for each other while they blissfully walked on the beach as Charlize strolled behind her 53-year-old man, wrapping her arms tightly around her new beau. Penn, meanwhile, kept a careful watch on little Jackson, who was running in front on the pair and playing with the two dogs also along for the outing.
According to a source, Theron and her son spent the weekend at Penn's beach house in Malibu, where the trio stepped out for a fun-filled afternoon together.
At one point, Sean, Charlize and Jackson stopped to look at the marine life on the beach, climbing on the rocks with the South African beauty's adopted son, while seeming like the image of the picture-perfect family. The group stayed at the beach a couple of hours, where the couple exchanged sweet kisses and pointed out the starfish to Jackson.
Theron was dressed cute and casual for the evening stroll, wearing tan Ugg boots, a cozy gray sweater and a pair of jeans, while Penn also looked low-key in a bomber jacket and basic pants.
Little Jackson, who stood out in a bright orange sweater, gazed at the lovebirds as they shared a sweet moment of PDA, proving the critically acclaimed actors only have eyes for each other. The eyewitness adds that the lovebirds were happy and hugging, and, although they knew they were being photographed, they did try to hide their love in front of the prying paps.
The couple was also very affectionate towards Jackson, and, in a particularly sweet moment, Penn picked up Theron's bundle of joy as the trio headed back to the car, giving the little guy a kiss before safely putting him in his seat (too cute!).
The A-listers were first romantically linked just after the New Year when they were spotted returning to Los Angeles after spending the holidays in Hawaii together.
Shortly after, they were seen grabbing coffee in Malibu, attending a screening of The Wolf of Wall Street and, according to a source, their relationship is seemingly on the fast track.
"They are spending night after night together and moving very fast," a source exclusively told E! News after the two first coupled up. "It seems like it's getting serious and that they can't get enough of each other" (Reps for Penn and Theron have declined to comment on their relationship status).
The lovebirds were most recently photographed hand in hand on Sunday, Jan. 26 while visiting a Bay Area nursery during a romantic getaway in San Francisco, Calif.
Prior to their trip up north, the good-looking couple was spotted grocery shopping together at Whole Foods in West Hollywood, Calif., on Jan. 22. Charlize's son Jackson was once again in tow for the outing, although the little one was kept perfectly entertained thanks to Penn, who playfully made silly faces at him while they all made their way around the store.
Sean and Charlize also recently attended Penn's Help Haiti Home gala, where, according to CNN's Piers Morgan, the Milk star told the British journalist he thought Theron was "a keeper."
We'd be willing to bet his feelings haven't changed.
