Do we spy a baby bump?

Isla Fisher and her husband, comedian Sacha Baron Cohen, are known for their steady silences when it comes to confirming personal news — they kept quiet regarding daughter Olive‘s birth, as well as their recent nuptials — but after Sunday’s photos, there seems to be little doubt that there’s a sibling on the way for their 2½-year-old!

The actress, 34 — who has kept her belly under wraps in recent days, covering it in loose tops, as well as her purse — stepped out in West Hollywood sporting quite the bump.

When contacted for comment, reps for the couple remained mum.

What do you think — is there a second baby on the way for Fisher and Baron Cohen?
