One Direction is expected to make a massive earning of $1 billion from their upcoming Where We Are world tour, and Harry Styles is already dropping cash on expensive art.

The 20-year-old recently blew over $30,000 on a series of Hayden Kays artwork. A source claimed that all the pieces Styles bought were "love and sex related" and was "probably to decorate his new home."

Each piece of art had witty humorous phrases such as "I will love you until the cold runs hot" and "If I wasn't straight I'd definitely be gay." Another one had a print of only seven words on a plain white background, simply saying, "I think about sex every sex words."

Each print cost the British boybander over $1,500 -- and since he bought 20 of them, the total price of the expensive shopping trip was more than $30,000.

Styles is clearly a fan of Hayden Kays' work -- the source revealed that the Midnight Memories singer purchased one of the prints back in 2012. "He purchased another love-related piece after his split from Caroline Flack," the source said.

The couple split in January 2012 after months of speculations of their relationship, which involved a 15-year age gap. Harry Styles is now rumored to be dating Kendall Jenner.

One Direction is set to go on their highly anticipated 88-date world tour later this year, and they will be the first to perform three consecutive nights at the 95,000-seat Rose Bowl stadium in California.
