The star passed away aged 72 after suffering a stroke while holidaying in Spain last August (15). In official reports obtained by Britain's The Sun newspaper, it's revealed Cilla has left the majority of her money to her boys Robert, 45, Ben, 41, and 35-year-old Jack, from her marriage to Bobby Willis. After paying $8.6 million (£5.95 million) worth of inheritance tax, each son will be left with more than $4.3 million (£3 million), according to the publication.

It doesn't stop there though, as the newspaper adds the three men will be receiving more thanks to Cilla's Spanish mansion, worth $2.8 million (£2 million), as well as her Barbados penthouse at $2.1 million (£1.5 million) - which aren't part of her U.K. estate.

Penny Walker, Cilla's housekeeper of over 30 years, has also been left a sum of $28,000 (£20,000), making her the only other person to be left money in the will.

"She adored her sons and treated Penny as part of the family," a source told The Sun.

Cilla rose to fame thanks to her successful music career and stints on TV shows such as Blind Date and Surprise Surprise. In December (15), Robert, who also worked as Cilla's manager, recalled his last moments with his mother.

"During the last two years she began to suffer fairly standard things that people as they get older would suffer," he said in a documentary about the late star's life. "Her hearing had started to go, so she had to start wearing hearing aids. Typical of my mum, she wouldn't wear them.

"The thing that really affected her physically was her arthritis. (The day she died) I'd gone for a jog, gone for a swim and stuff. She was sitting around having a glass of champagne killing herself laughing at Jeremy Kyle - without the hearing aids obviously - so blaring out across Marbella."
