Pregnant Presley: Lisa Marie shows off her bump

The 40-year-old singer, married to guitarist and music producer Michael Lockwood, was snapped leaving the Waverly Inn restaurant in New York City's West Village on Saturday evening.

Presley's agent confirmed rumours the singer was pregnant in March after she was first pictured with a bump in her belly, and said: 'The couple are incredibly overjoyed'.

Lisa Marie's marriage to Lockwood is her fourth in 20 years. She has two children, Danielle and Benjamin,  from her first marriage to musician Danny Keough, which lasted from October 1988 until 1994.

Her marriage to singer Michael Jackson, who she wed in May 1994, lasted just 21 months and her nuptials with actor Nicolas Cage lasted just three.

Lisa Marie, 40, was then engaged to rocker John Oszajca before marrying Lockwood in Japan, in January 2006.

Since the age of 25 she has managed the Elvis Presley Trust, with support from her mother Priscilla.

The King's affection for his daughter was well known. Until his death when Lisa Marie was nine, he would take her on trips on his private plane, called Lisa Marie, and she owned a personal golf cart to move around their Graceland estate.
