Sir Roger Moore used to think Zsa Zsa Gabor's bottom was too big.

The 86-year-old actor attended an event with the 97-year-old actress in their heyday when they were both signed to media company MGM, and the James Bond star admits that while he found the legendary star to be ''exquisitely beautiful'', he wasn't quite so keen on her shapely rear.

In an extract from his upcoming memoir, 'Last Man Standing: Tales From Tinseltown', which has been serialised by MailOnline, he said: ''Zsa Zsa Gabor is perhaps better known for the number of her marriages rather than anything else, and I was once coupled with her by MGM - albeit platonically.

''It was the studio's habit of partnering their contract artists with each other to attend events, premieres and dinners, purely for publicity purposes.

''She was exquisitely beautiful, if a little large in the lower rear region I felt - well, not literally felt, you understand.''

Roger uses his upcoming book to dish the dirt on several well-known Hollywood actresses he used to mix in the same circles with including Bette Davis, who he claims used to choose who she wanted sacked from projects she starred in and was ''standoffish'' on set.

Speaking about Bette's role in West End play 'The Anniversary', he said: ''A very talented, award-winning young director named Alvin Rakoff was signed to helm this new Hammer production, and the British cast were told that Miss Davis was to command their utmost respect, but they were not to approach her directly on set.

''Furthermore, on her first day, they were given instructions to gather round and applaud the star as she made her entrance.

''Within a few days it was clear that Bette was not only standoffish with her co-stars but was even unwilling to engage in any form of dialogue with Alvin.''

Roger also claimed: ''Sheila Hancock had the dressing room next door to Miss Davis' and she was able to hear the conversations through the radiator pipes and - almost on a daily basis - heard whom Miss Davis demanded to be sacked next.''
