Former Westlife star Brian McFadden regrets acting like a diva at the start of his solo career - realising his behaviour was "arrogant". The Irish singer left the boyband in 2004 to pursue a solo career, and was delighted when his first single Real To Me topped charts around the world. But MCFadden admits he allowed success to "go to (his) head" and take advantage of the things he missed out on while he was in the band. He says, "I was very arrogant. "I had to have first-class flights for me and my team that I didn't need, but I wanted to take advantage for the things they'd done in the past. "I even had a hairdresser on a retainer of GBP100,000 a year. It was ridiculous."
