The `You Oughta Know` singer - who this week announced she is expecting her first child with her rapper husband Souleye, real name Mario Treadway - went to see her physician for another reason when he gave her the happy news.

During a TV interview with Chelsea Handler, she said: "I went to the doctor and he said, `Well this looks like the scan of a pregnant lady.`

The `Chelsea Lately` host then put it to Alanis that she had "obviously gone to the doctor because you thought you were pregnant?"

To which the rock star replied: "No actually I thought I wasn`t. But I mentioned in passing that I was a bit late, so he said, `Well let`s just take a quick look.` "

Even after being told by her doctor she was expecting, 36-year-old Alanis - who is five months into her pregnancy - still couldn`t believe it.

She explained: "I said, `But there`s still a chance I`m not though, yes?` And he said, `About as much chance as me getting a sex change.`

"And I said, `So when are you getting a sex change!?` "

The musician also revealed she was instantly attracted to Mario the first time she met him at a meditation ceremony at her house.

She said: "He walked in and I thought to myself, `Wow he`s incredibly sexy.` "

Alanis - who married Mario at her Los Angeles home in May after dating him for just eight months - has also tweeted her followers her joyous news, saying: "Yes, happy news, i`m pregnant :) we`re so excited to start our family.... xo a (sic)"
