Leonardo DiCaprio is taking full advantage of southern California‘s current summer heatwave.

The 45-year-old Oscar winner was spotted grinning ear-to-ear while enjoying a relaxing day with his 23-year-old girlfriend Camila Morrone and some pals on the beach in Malibu on Monday.

Typically one of Hollywood’s more reserved stars, Leo seemed to have no qualms about letting out his inner child while splish-splashing in the Pacific Ocean.

Leo put his former teen heartthrob beach body on display in a simple but classic pair of blue swim trunks.

He opted to catch some rays shirtless but made sure to protect his face from the sun wearing a pair of sunglasses and a California baseball hat.

DiCaprio let loose in the water and was seen running, splashing and jumping over frothy crashing waves like a pro.

He waded around in the salt water and dunked himself in up to his shoulders to get a break from the sizzling heat.

Remarkably, the Titanic star didn’t loose his hat or glasses while out for his swim.

Leo is clearly a beach lover as he was spotted flashing his megawatt smile and roaring with laughter at one point.

This is the second time in just a handful of days that the Once Upon a Time in Hollywood star was seen taking a day off at the beach.

Over the weekend he and his dad, George DiCaprio, 76, spent a day in Malibu together along with a pint-sized family member.

One person missing from that outing was Morrone – with whom he has gotten serious during the coronavirus pandemic.

Camila and Leonardo originally met through her stepfather, Al Pacino, 80, who was married to her mother Lucila Solá, 44, from 2008 until their divorce in 2018.

The Hollywood couple has been together since 2017, but only made their red carpet debut during the 2020 Academy Awards in February.

Moving on up: According to reports, Camila and Leo have been enjoying the past few months of lockdown together in his Hollywood home. The pair have even adopted a pup together

It was the first time the Wolf of Wall Street star brought a date to the show since bringing his ex girlfriend, Gisele Bundchen in 2005.

According to reports, Camila and Leo have been enjoying the past few months of lockdown together in his Hollywood home. The pair have even adopted a pup together.

‘He is usually very independent, spends lots of time with friends, but because of the lockdown, he has mostly spent time with Camila,’ a source told People in June. ‘He loves being with her.’

‘They are very close,’ the insider went on, adding that Leo seems ‘serious’ about Morrone. ‘Leo has spent 24/7 with Camila for months at his house.’

‘They’re always together, but like maintaining privacy,’ another source told Us Weekly recently. ‘They’re really great for one another and have been enjoying this time together off the grid.’

While they have a 22-year age-gap, that hasn’t seemed to affect the highly private couple.

Since Hollywood has been basically shuttered due to COVID-19, Leo has had an unprecedented amount of time on his hands but has several major projects on the docket for 2021.

He is set to star as U.S. President Teddy Roosevelt in the film Roosevelt, will play America’s first serial killer Dr. H. H. Holmes in a television adaptation of the book The Devil in the White City, and has starring roles in The Black Hand and Scorsese’s Killers of the Flower Moon.

He also recently signed a major multi-year first look deal with Sony Pictures, according to a report in Variety.

The environmental activist is also getting involved in the upcoming presidential election and, on Tuesday, he took to social media to share information on how people can safely cast mail-in ballots this November.
