Luciana Gimenez Morad is adamant she and Sir Mick Jagger did not have sex and conceive their son in a dog's ''kennel''.

The 45-year-old former model's tryst with The Rolling Stones rocker in 1998 resulted in 16-year-old Lucas being born and led to the end of Mick's marriage to Jerry Hall in 1999.

Writer Christopher Anderson in his book 'Mick: The Wild Life and Mad Genius of Jagger' - released in 2013 - had claimed the pair hit it off because Luciana was one of only a few English language speakers at a party held for the 'Satisfaction' singer in Rio de Janeiro.

He wrote that after Mick stepped outside the lavish bash to ''take some fresh air in the garden with Luciana'' the pair ended up ''shagging in the kennel''.

However, the Brazilian beauty insists the rock 'n' roll tale is untrue because she is too ''refined'' to indulge in coitus in a canine's home.

Speaking to Brazil's Glamour magazine, she said: ''I did not get pregnant with Mick [Jagger] in a doghouse ... Can you imagine Mick Jagger ... inside a kennel, me on top of him and the people at the party all watching? I am a super-refined gal and would never do this.''

Following her fling with Mick, Luciana went on to marry RedeTV! owner Marcelo de Carvalho in August 2006 and they have a child together, four-year-old Lorenzo, while he has three kids from his first marriage.

Mick is almost as famous for his love life as he is for his music and has a total of seven children with four different women and five grandchildren. He became a great-grandfather in May 2014 when his 43-year-old daughter Jade Jagger's child Assisi gave birth to her own daughter Ezra.
