A love rat actor who romanced two sisters at once has seen the error of his ways - after they published a BOOK exposing his deceit.

The lothario, known only as 'Mike', got a shock after discovering the women had penned a book about his ''dirty tricks''.

'Two Sisters, One Boyfriend! And How to Deal with Your Own Boyfriend' brands the 27-year-old a ''cheat'' and a ''liar'', and adds: ''Other women should beware of him''.

The jobbing thespian romanced pretty Cindy Rhyme, 23, for seven weeks while also seeing her sister Sheila, 26, at the same time.

But the penny finally dropped when Cindy took Mike to a party and introduced him to Sheila - who promptly slapped him in the face.

The furious pair, both professional actresses, seeked revenge ''immediately'' by writing a 'warts and all' expose of his two-timing ways.

Speaking yesterday (Fri) from the home they share in central London, the sisters said the affair had not affected their own relationship.

But Cindy said: ''Being cheated on can be a very difficult time for anyone, let alone finding out it is with your own sister.

''Both of us thought that Mike was the one and we wanted to stay with him forever.

''We have remained strong through this situation, and our relationship has not been affected.

''The book is a book about love and trust among women and men and aims to help girls and women to enjoy better - and more honest - relationships.''

Sheila met Mike in early April this year at a nightclub in London and instantly fell for his ''charm'' and love of the theatre.

She said he promised her ''the world'' and vowed to be ''the loyal and loving partner'' she craved.

But within weeks, Mike met another woman on a night out with pals who, by sheer co-incidence, was Sheila's younger sister Cindy.

He dated both sisters for some seven weeks without being caught, despite giving both his real name.

''Neither of us saw Mike at the same time, so we had no idea that he was cheating on us,'' Sheila said.

''We knew we were both seeing a chap called Mike, but we would never have guessed that it was the same person.''

But his infidelity was revealed in late May when Cindy asked him to accompany her to a friend's birthday party.

She introduced him to Sheila, who was also a guest, as her boyfriend. They confronted him about his ''dirty tactics'' before Sheila threw her drink in his face and slapped him across the cheek.

Cindy said: ''I didn't know whether to laugh or cry. It was such a preposterous situation.
''There I was introducing my 'wonderful' boyfriend to Sheila, and there was Sheila shouting and screaming at Mike.

''I must admit she took it worse that I did. Sheila went mad and then threw her wine all over him. She then whacked him across the chops before he finally got the message and disappeared.''

Despite the shock, the plucky pair - who are now single - decided to put pen to paper in a bid to help other women in the same situation.

They spent the next five months writing Two Sisters, One Boyfriend! And How to Deal with Your Own Boyfriend, which they describe as the ''essential handbook to relationship woes''.

''We wrote this book hoping to help women to live better relationships in love, friendship and sisterhood,'' Sheila said.

''With our experiences and and real life stories we hope that readers will take away some valuable guidance from our book.''
