Harry Styles is missing his mother while on tour in the US.
Although the One Direction singer is enjoying huge success in America - with the group's album 'Up All Night' recently reaching the number one spot in the US billboard charts - he has been texting his mother up to five times a day because he is so homesick.
A source told the Daily Star newspaper: ''Harry has been badly missing home. Not a day goes by without him texting his mum up to five times.
''It's been a struggle adapting to the enormous success the boys are having over the pond, as well as getting used to living in hotel rooms constantly. He misses home.''
In particular, keen amateur chef Harry, 18, has missed meal times with his family.
The source added: ''He especially misses cooking for his family. Mexican food is his specialty. Being in the kitchen is his main way of relaxing and escaping stress and he's started getting withdrawals on the road.''
Harry famously dated 32-year-old TV presenter Caroline Flack earlier this year and pals say older women love him because he's a big kid at heart.
An insider said: ''He's like a kid in so many areas of his life which is why older women just love to mother him.''
