Happy Tulisa or Sad Tulisa?

Tulisa Contostavlos seemed very happy when she arrived at Los Angeles yesterday, and the 23-year-old looked always stylish in sports chic outfit of skinny jeans, heeled trainers, a checked shirt and blue jacket. And her yellow clutches handbags or handbags clutches highlight her low-key ensemble.

However, the X Factor's judge's cheery outward appearance came just hours after it was claimed her ex-boyfriend Fazer's demands for marriage and a baby led to their split after an 18-month relationship.

According to an insider Fazer and Chloe, who met through mutual friends, were texting each other when the 25-year-old was recently on holiday with Tulisa. After Tulisa confronted him about the Topshop heiress he is then alleged to have questioned her commitment to their relationship. A friend told Closer magazine that Fazer said: 'I want marriage and a baby and it seems all you want is fame!' The insider told the publication: 'He told her if she wasn't prepared to commit to starting a family, she couldn't tell him who he could or couldn't speak to.'

Fazer, real name Richard Rawson, is also said to have asked the chart topper to quit her role on X Factor. A source told heat magazine: 'He told her that he thinks she should quit the X Factor, and that she'd changed. It really cut through Tulisa and she started to cry.'

Earlier this week, Tulisa confirmed that she will be releasing a solo single in the next few months. With her group N-Dubz on hiatus and her recent split from Fazer, it's the perfect time for Tulisa.
