Lisa Marie Presley is "overjoyed" to be expecting a child with husband Michael Lockwood .

The 40-year-old daughter of late rock legend Elvis Presley has two teenage children from her previous marriage to Danny Keogh - Riley, 18, and 15-year-old Benjamin - but this is her first with Lockwood.

Presley’s representative confirmed she is pregnant, telling People.com, "The couple are incredibly overjoyed."

Presley wed musical director Lockwood in 2006 after her three previous marriages all ended in divorce. The singer split from Keogh in 1988; she went on to marry Michael Jackson in 1994, breaking up with him 21 months later, and actor Nicolas Cage, who filed for divorce three months after they married in 2002
