LONDON (Court TV) — It's official: Mick Jagger and Jerry Hall have called it quits. But in a surprise twist, the Rolling Stone lead singer and the Texan-born model agreed Friday they were never really married at all.

In what was deemed a harmonious split, the former couple proclaimed their 1990 Hindu marriage null and void and not sound under English law.

In a statement read during a 12-minute hearing in the High Court in central London, attorneys for the couple said the one-time dynamic duo had reached a "mutually acceptable legal and financial settlement."

"Mick Jagger and Jerry Hall are determined that their friendship and mutual respect will endure. They will always be linked through the great shared love they have for their four children and their determination to both play their full part as parents," according to the statement.

Hall filed for divorce in January after a Brazilian model claimed she was pregnant after a fling with the British rocker. Jagger's publicity agents had said he would contest Hall's petition on the grounds that their Indonesian marriage was not legally valid.

Friday's hearing had been scheduled to arrange an agenda for a full hearing of Hall's petition for divorce.

The settlement avoids a long, costly, and very public court battle. Details of the financial settlement were kept secret, but British tabloids have reported that Hall was seeking a $50 million settlement from Jagger's estimated fortune of $240 million.

According to the BBC, attorneys for Hall were expected to claim her 1990 marriage in Bali to Jagger was indeed valid. Even if Jagger were successful in having the marriage voided, Hall's lawyers were ready to claim that she was entitled to recoup the same settlement as if she had been his wife.

Although their wedding ceremony took place in 1990, Jagger, 55, and Hall, 43, have been together for 21 years.

Hall was represented by Mishcon de Reya, the same law firm that Princess Diana used in her divorce from Prince Charles.
