For Robin Thicke and girlfriend April Love Geary, age is just a number. The “Blurred Lines” singer is nearly 20 years older than his 20-year-old girlfriend, but the couple is going forward with their relationship. Geary and Thicke were spotted vacationing together in St. Barths, the U.K.’s Daily Mail reported Friday. Photographers were there to capture the couple splashing around the beach and some of the pictures showed the model holding Thicke’s 5-year-old son Julian.

Before they made it to the island, the couple was seen flirting at Los Angeles International Airport, the New York Post wrote, according to OK! Magazine. “He was standing in the aisle as people boarded, leaning over to make out with her,” a witness said. “He was blocking the way. She was giggling. It was obnoxious. He was just like, ‘Oh, sorry.’ He knew he was being disruptive.”

Geary posted multiple pictures of their vacation to her Instagram account. Several of them featured Thicke. “Beach & my boo,” she captioned one picture. “My tan island chauffeur!” she said about another.

It didn’t take long for Thicke to move on from ex-wife Paula Patton. The former couple finalized their divorce two months ago.

Patton and Thicke split after he was reportedly caught cheating. At the time, he supposedly begged for her to come back and tried to woo her with public apologies and onstage acknowledgments. He even wrote the song, “Get Her Back,” about Patton, complete with lyrics such as "I should've kissed you longer / I should've held you stronger." He then sang the song at the 2014 Billboard Music Awards.

But it didn’t work. Patton, 39, told Meredith Viera she was getting “used to the change” after her divorce was finalized. "I went from my parent's house to moving in with Robin, and now I'm becoming an adult," she said in the interview, according to People. "I'm really, like a real woman now."
