Niall Horan has Twitter chat with Katy Perry

One Direction‘s debut album Up All Night shot straight to No 1 in the US iTunes chart last night.

The boys – who have just finished supporting Big Time Rush on tour in America – reportedly reached the top spot just 27 minutes after their record was released.

‘Guys you are unreal, directioners are incredible, love you all xx,’ Tweets Niall Horan, 18.

And back in the UK, 18-year-old Harry Styles‘ mum is chuffed with their success: ‘Wow!! Fantastic news to wake up to! So proud @Harry_Styles @onedirection WELL DONE boys – you’ve worked hard & you deserve this. Love you xx.’

Pop star Katy Perry is also chuffed with 1D‘s achievements across the pond.

The 27-year-old was on The X Factor judging panel in 2010 to see Niall‘s first audition.

Katy called him ‘adorable’ but wasn’t sure he was old enough – and when she reluctantly put him through to boot camp she told him: ‘Don’t let us down’.

‘@NiallOfficial congratulations, you didn’t let me down! xo,’ Tweets Katy.

Humble Niall soon replied: ‘Hey katy,thank you,let’s hope it holds out this week!Thank you for putting me thru!we’ve been working hard,I won’t let you down.’
