Colin Farrell and Alicja Bachleda

Alicja Bachleda-Curus's mom is sipping tea and chatting to her friends over cakes when the postman arrives.

"What could this be in such a bulky package" she thinks to herself.

She opens with anticipation to discover a tape inside the sealed envelope.

Curiosity gets the better of her and she flips the tape into her video recorder and within minutes she is seeing her daughters famous boyfriend naked and doing all sorts of dirty things to a woman who is not her daughter - something we are sure she is counting her blessings on.

Farrell, 34, is romping with former gal pal and model Nicole Narain.

Mrs. Bachleda-Curus received the tape shortly after Farrell began dating her daughter but Colin and Alicja are only speaking out about the horror of it all now.

"It was a very embarrassing moment," said Colin.

The actress, 27, said: "I didn't know about it because I don't follow gossip nor look for it on the Internet."

Um Colin maybe you should have honest with her from the start!

Nice way for her to find out- from her mother!

Alicja and Farrell have a one-year old son Henry and are supposedly doing a very steady line.
