9021 ... oh baby!

Shannen Doherty stopped to get some groceries in Malibu and it looks as though the former 90210 star has a baby bump.

The 41-year-old actress married her third husband Kurt Iswarienko last year. Sounds like someone may be ready to start a family!

UPDATE! - Shannen just Tweeted this response to our photo:
    sad paparazzi & bad gossip sites, I'm a size 2, not sporting a baby bump. That's simply the hamburger I wolfed down 2 minutes prior.Pathetic

Sorry, Shan! We were hoping for some happy news ... on the other hand, a good burger can be really happy too!
