Harry Styles, Cara Delevingne Tattoo War? [PHOTOS]: One Direction Singer 'Desperate' for Rumored Ex-Girlfriend's Invite to Epic 21st Birthday Party in Ibiza

In early 2013, rumors surrounding why One Direction's Harry Styles broke up with Taylor Swift led many to one answer: English model Cara Delevingne. The two were spotted hanging out and the rest is history. Though some sources claim Harry was not Cara's type or whether they dated or not, the two have at least remained friends throughout the year. Unfortunately this friendship hit some sort of snag when Styles did not receive an invitation to Cara's 21^st birthday bash she is having next month in Ibiza. If these two are "cool," why wasn't the pop star invited?

According to a One Direction insider on the "Take Me Home" world tour: "Harry kept hearing about Cara's party through their mutual pals. He started to wonder what he'd done wrong. So he texted asking Cara why he wasn't invited because he thought they were still friends."

"He then cheekily added: 'Can I come?' Naturally she was mortified, and quickly apologized," the source said. "Cara told him she'd only left him out because she thought he'd be too busy on his tour to come anyway. But Harry assured her he can get a private jet to the rave on the 24th, which is two days after her birthday."

Oh great! It looks like the two are indeed friends and have cleared up this little mishap.

Though Harry wasn't done with Cara, according to the insider. He explained that his next tattoo (for his ever-growing collection of body art) would blow her latest "Made in England" ink out of the park.

Check out Cara's latest tattoo that she recently talked to Prince Charles about. She also asked the Duke of Cornwal if he had any body art, to which he had a good laugh about.

"Harry jokingly told Cara he will unveil a new tattoo that puts her new 'Made In England' stamp to shame," the source continued. "He hinted it may have something to do with James Bond and said it will be his biggest yet."

So now we have another Harry tattoo to look forward to! Hopefully he doesn't take any queues from band member Zayn Malik, though.

Here are Cara's other tattoos:
