JLS celebrated their chart-topping success with family and friends last night.
The X Factor boyband sold over 100,000 copies of their debut single 'Beat Again' last week to enter yesterday's UK singles chart at number one.
Speaking to DS a few hours before their chart position was confirmed, group member Marvin Humes said: "Once we get that phone call from Radio 1, that's when we can pop the champagne.
"Tonight we're just going to be with our family and friends - people who've been with us from day one and have supported us and got us to where we've got to."
