The 32-year-old singer-turned-fashion mogul was expecting again and she made the baby news official by posting a photo of her seven-month-old daughter Maxwell on micro-blogging site Twitter where the tot is sitting in the sand during a festive vacation in Hawaii behind the message 'Big Sis', reported Contactmusic.
The 'Irresistible' hitmaker, who is engaged to NFL player Eric Johnson and gave birth to Maxwell in May, had used a tweet on Halloween in 2011 to announce that she was pregnant with daughter Maxwell.
Little Maxwell was born in May, just before her famous mother signed up to front a lucrative new diet campaign for WeightWatchers.
