Baby bump watch in Hollywood is serious business - get photographed in a loose-fitting top and/or after a filling lunch and the next thing you know, people are asking if you're pregnant.
Which is precisely what happened to "How I Met Your Mother" actress Alyson Hannigan.
The 37-year-old was caught on camera with what was speculated to be a baby belly while hanging out in Malibu over the weekend with her husband and 2-year-old daughter.
Except there's no baby, Hannigan's confirmed.
"NO, I'm not pregnant! I just ate too much carnival food, that time of the month, hurt my back & couldn't suck my gut in, & need 2 do cardio!" she tweeted on Sunday.
"And I'm NEVER gonna wear that shirt again!" Hannigan promised, even admitting, "I do LOOK pregnant in that photo!"
