ling exercise sport cycling bump pregnant

Katie Holmes headed to her cycling class in Brentwood on Sunday, and she seemed to be showing off a much fuller tummy under her loose-fitting tank.

The fitness-obsessed actress is always in flawless shape, so we can't help but wonder if Mr. and Mrs. Tom Cruise may be prepping to make an announcement any time soon?

The Hollywood power couple are getting ready to celebrate five years together this November, and baby No. 2 may be just the perfect anniversary surprise for the happy couple!
