Harry Styles has again been spotted out and about late last night with a beautiful blonde after the House of Holland Fashion show. Contrary to early reports that it's another quick fling, the blonde who tagged along with Styles, Matthew Mosshart, Nick Grimshaw and Kelly Osbourne was actually his older sister, Gemma Styles. The fashionable siblings prove they've certainly got "Style."

The One Direction curly haired cutie made a point to attend quite a few fashion shows. Over the weekend, Harry along with his older sister, Gemma Styles attended the House of Holland fashion show at the Somerset House. After the event, the Styles siblings headed out with Matthew Mosshart, Nick Grimshaw and Kelly Osbourne.

The five enjoyed a round of drinks at the Primrose Hill pub. Before Harry left the area, the 1D cutie made friends with an equally adorable pup. Onlookers claimed Harry had even tripped over the pup but rather than look out for his own safety had immediately checked to see if the dog was alright. This earned a lot of "aw" from "Directioners."

Nick Grimshaw, Matthew Mosshart and Kelly Osbourne separated from the siblings and headed off to another fashion show. As for Gemma and Harry styles, the siblings jumped onto their vehincle and drove off to spend the weekend together. Where was the rumoured girlfriend, Cara Delevingne?

Well, Kelly Osbourne attended the W Magazine party that night which was hosted by Harry's alleged girlfriend. The two have not officially spoken up on the status of their relationship but some "Directioners" are quick to say they aren't really together.

"Of course he might profess his love for her - and he has done that on many occasions - but she's heard it all before. 'He said that to her just a month before he went public with Taylor, so I imagine she's learned her lesson," says a source to Look Magazine.
