He's adorable! Niall charms Demi's sisters on day out at the pier

ONE Direction singer Niall Horan has taken things with Demi Lovato to the next level, by enjoying a day out with the pop star's family.

The Mullingar native made the most of his time off from the band's US tour over the weekend and took his rumoured girlfriend Demi's sisters for a trip to Santa Monica Pier in California.

The 18-year-old clearly went down well with the US X Factor judge's siblings and Niall was even branded "adorable" by Dallas Lovato and Madison De La Garza -- the actress who plays Juanita Solis in Desperate Housewives.

Taking to her social networking site after the day out, Dallas tweeted Niall apologising if she embarrassed him with her teasing over Demi (19).

Although the two claim to be 'just friends', Niall admitted on a US radio show that he's been enjoying a number of Skype dates with Demi recently.
