Curvy Tulisa Contostavlos slammed for 'dad-dancing' and frumpy outfit during BGT performance
The singer, who has new fuller curves, was heavily criticised for her moves on stage and her choice of outfit on the night - a bodycon dress with chiffon tassels.
And her unflattering pumps with ankle straps made Tulisa - who was recently crowned the sexiest woman in the world - look frumpy.
'Oh, Tulisa. Autotune, flat shoes and dad-dancing. I am disappoint #bgt,' Tweets one viewer.
Though Tulisa was also accused of miming along to the dance tune, her spokesman confirms she was 'one hundred per cent singing live'.
And the N-Dubz star seemed pretty pleased with her performance as she headed away from the studios en route to her party to celebrate her record topping the charts.
'It's always been a childhood dream of mine to get a No.1 single! Thank you so much to everyone who bought Young. Xx,' Tweeted Tulisa, 23.
