Harry Styles Goes Shopping With Taylor Swift's Mum As One Direction Continue US Visit
The singer enjoys a night out watching Haim in Los Angeles as One Direction return to America before Christmas.
One Direction's Harry Styles has travelled to America to join Taylor Swift ahead of Christmas.
The 'Live While We're Young' star's relationship with Taylor has rarely been out of the spotlight since it emerged they were dating last month.
And they already appear to have taken their romance to the next level after Harry was spotted grocery shopping with Taylor and her mother Andrea in Los Angeles on Wednesday (21st December).
Harry, who was wearing a band t-shirt for British indie rockers The Cribs, briefly visited Ralph's before returning to the Swift family home.
It is not clear if the One Direction star is planning to stay in America for the Christmas period, or return to his family home in Cheshire, where he took Taylor earlier this month.

However, Harry looks eager to enjoy his time in the US – he went to watch the hotly tipped band Haim at the Troubadour last night and was quick to praise their performance on Twitter.
He wrote: "Just saw @HAIMtheband in LA.. They are ridiculous. They're gonna have a big year next year.. So sick."
Harry and the rest of One Direction's trip to America comes as it was confirmed that the group's second album 'Take Me Home' has already sold over one million copies in the US.
