This is just adding to our suspicions...

Ben Affleck and Lindsay Shookus dropped by a medical building together yesterday in LA, just days after we photographed her looking like she was hiding a baby bump. Why else would you accompany your significant other to the doctor's office unless you had a bun in the oven?

The SNL producer also isn't helping to downplay the rumors with her outfit choice. We all know that ruffles and peplums and the like are the best styles for hiding a growing midsection.

Their relationship is already serious, and she just recently moved into his $19 million Brentwood mansion. Starting a family would be the next logical step... well, other than marriage which doesn't seem to be at the top of most people in Hollywood's priority lists these days!

A source tells X17:
    "Ben and Lindsay are a lot more serious than people realize, as they've secretly been together for years. She's always told Ben she's not getting any younger, and she wants her daughter to have a sibling. They both know getting pregnant would mean tons of headlines and attention, which they're dreading, but they also feel like they shouldn't live their lives with concern for public perception."

Guess we'll have to wait and see if there's a baby Batman on the way!
