Leonardo DiCaprio is 22 years older than his girlfriend Camila Morrone. Here's a timeline of their relationship.

An anonymous source told Us Weekly that the then 20-year-old model and DiCaprio were "hooking up." However, a "source close to Morrone" was quoted in the same report as saying that Morrone and the "Romeo + Juliet" actor were just friends.

Morrone and DiCaprio were seen leaving a private jet together in Los Angeles, after presumably spending the holidays with one another in Aspen, Colorado.

According to E! News, the couple visited Italy and France during their yacht vacation, stopping frequently to swim, snorkel, and jet ski.

A source was also quoted in the article as saying that DiCaprio and Morrone have a "very relaxed relationship." The pair even spent time with Morrone's mom, Lucila Sola, during a stop in Antibes, France.

Morrone was pictured wearing a dark overcoat with a tan turtleneck underneath, while DiCaprio kept things low-key with a black baseball hat and sunglasses.

Photographers captured the two talking and laughing during the match.

Even though they were in Cannes at the same time, the couple frequented separate events and didn't pose for red-carpet photos together.

Morrone was at the festival to promote her drama "Mickey and the Bear," and DiCaprio's film "Once Upon a Time in Hollywood" had its premiere at the French film festival.

DiCaprio was later spotted taking photos of Morrone outside of the Hotel du Cap-Eden-Roc in Antibes, a popular destination for many A-listers during Cannes.

The model received backlash from some after she shared images of actor Humphrey Bogart with his wife, actress Lauren Bacall, to her Instagram account. Morrone captioned the pictures of Bogart and Bacall, who had a 25-year age difference between them, "A love like this."

After some commenters took issue with Morrone's post and her relationship with DiCaprio, the model responded on her Instagram stories.

"I just hope on this Friday that people learn to live with a little less hatred," she said.

The same month, a source told People that the two were becoming "pretty serious."

"It's definitely not a casual relationship. Camila spends a lot of time at his house," the source said, adding that Morrone had met DiCaprio's parents "long ago."

"There's so many relationships in Hollywood — and in the history of the world — where people have large age gaps," Morrone said in an interview with the Los Angeles Times. "I just think anyone should be able to date who they want to date."

The actress also expressed her frustration that the attention on her relationship was detracting from her work in her film "Mickey and the Bear."

"I feel like there should always be an identity besides who you're dating," she told the Los Angeles Times. "I understand the association, but I'm confident that will continue to slip away and be less of a conversation."

"More exposure leads to more judgment and negativity," the model said of her relationship with DiCaprio during an interview with the Wall Street Journal magazine.

"It's a little bit of a bummer because you're really trying to do good work and be nice and be a good person, and in the meantime… people wish negative things upon you," Morrone added.

Though they didn't walk the red carpet together, DiCaprio and Morrone were both seated in the front row during the ceremony. The "Wolf of Wall Street" star was pictured wearing a classic black tuxedo, while Morrone stunned in a strapless pale pink gown.

According to Page Six, DiCaprio was one of the only attendees to wear a mask during the celebration, which appeared to be Western-themed.

Other party guests reportedly included Nina Dobrev, Shaun White, and Kevin Connolly.

Morrone and DiCaprio reportedly splurged at an Italian market in Boston ahead of the holiday. Among the items the couple bought were pasta sauces, fig jam, homemade potato chips ,and more, according to People.

DiCaprio even tried to get some cannoli for the couple's celebration, but the store was apparently sold out.

Around this time, the pair were also rumored to be living together, after a source told E! News that DiCaprio was "settling into this domestic life" with Morrone."

DiCaprio, in a gray mask and LA Dodgers cap, and Morrone, in dark sunglasses, watched a match between Daniil Medvedev of Russia and Novak Djokovic of Serbia.

The two were seen embracing, kissing, and playing in the water with their dog, Jack, in the photos published by the Daily Mail.

According to Just Jared, DiCaprio spent time catching up with friends — Tobey Maguire and Lukas Has were also reportedly in attendance — at a beachside venue, while Morrone walked her dogs near the water.
