40-year-old daughter of Elvis Presley gave birth by Caesarean section on Tuesday, a statement said.

“Babies and mom are happy and healthy and resting at home,” it added. The girls weighed 5lb 15oz (2.7kg) and 5lb 2oz (2.3kg).

Presley, who is married to producer Michael Lockwood, lives in Los Angeles. She has a 19-year-old daughter and 15-year-old son from a previous marriage.

There may be many advantages to being Elvis Presley’s daughter, but at times your genetic inheritance may not be one of them.

 The Daily Mail reports that at a New York homeless charity event this month Lisa Marie, who has in the past tended to take after her still-youthful mother Priscilla - star of the Naked Gun series of films - appeared “bloated”.

Her father Elvis famously died of a suspected heart attack in 1977, when weighing as much as 250lb (18 stone).

While a long-standing amphetamines and painkillers habit are reported to have contributed to his untimely death - he was just 42 - his penchant for snacks such as the bacon, peanut butter and banana deep-fried sandwich was well-documented.

It is reported that he would eat one made from a hollowed-out loaf intended to feed eight people at a single sitting.

Miss Presley’s appearance is in stark contrast to last summer, when a trim Lisa-Marie appeared in a virtual-reality duet with her late father.

The singer-songwriter, who counts Nicolas Cage and Michael Jackson among her three ex-husbands, is currently married to Michael Lockwood, her guitarist and producer. She has released two platinum-selling albums, and in August 2007 her duet with Elvis on his 1968 single “In The Ghetto” reached number one on the iTunes video sales chart in the first week of its release.

A third album, as yet unnamed, is due to be released at some stage in 2008.
