Martha Stewart Jinxes Yankees No-Hitter

NY Yankees pitcher Michael Pineda was on the verge of throwing a no-hitter Monday ... until Martha Stewart ruined it.

Pineda was perfect through 6 innings against the Tampa Bay Rays -- and at the top of the 7th inning, Stewart decided to tweet about.

"It's top of the seventh here at yankee stadium and the Yankees are pitching a perfect game versus the Tampa rays."

YOU JINXED IT, MARTHA!!!! NEVER TALK ABOUT A NO-HITTER!!

Two batters later, Evan Longoria got a hit and broke up the no-no.
