Alanis Morisette's Prenatal Workout

She's absolutely glowing! Mom-to-be Alanis Morissette was all smiles as she headed to the gym in Santa Monica today (August 17).

The songstress - who has sold more than 40 million albums worldwide - and her new hubby Souleye are expecting their first child together.

The 36-year-old Ottawa native recently admitted that she wasn't expecting to be expecting. The doctor said it "looked like" she was pregnant. "And I said, 'There's still a chance that I'm not, though, yes?'" she says. "And he said, 'About as likely as my getting a sex change.' And I said, 'So, when are you getting your sex change?'"
