Could they be any cuter?

Taking the opportunity to unwind before their back-to-back performances in San Jose and Oakland this week, One Direction's Harry Styles and Niall Horan enjoyed a round of golf in San Diego, on Tuesday afternoon.

After wrapping up their game, the UK boy band members were literally swarmed with young girls on their golf cart, but the boys took it in stride and stopped to sign autographs for every single one of their adoring American fans!

Just before they traveled to the States for their tour, the boys battled it out on a UK golf course, and Harry definitely kicked Niall's butt. The 18-year-old heartthrob shared via Twitter: “I’d like to apologize to @jackrobbo100 for beating him with my 4skins to his 2skins round the golf course.”
