After serving up some seriously stiff pre-Oscar interviews, Kathy Ireland says she's not giving up her day job.

The 46-year-old supermodel-turned-design-guru shocked viewers Sunday night as she awkwardly welcomed the likes of "Precious" star Gabourey Sidibe and Zac Efron to the red carpet, leading many to question her behavior on Twitter.

According to UsMagazine.com, some viewers called her a "hot mess," while others cast her as their vote for "best use of medication."

Today, Ireland shocked even more by personally responding to each Twitter critic.

"Acting isn't a strength of mine," she wrote to one commenter, "Design is my world. Not an actor and have movies 2 prove it."

To another, she denied the suggestion that she's pregnant - calling it a compliment, of all things.

"No Angel...3 kids and not pregnant...love being pregnant though. Thanks for the complimnemt [sic]," she wrote.

Despite some of the nasty accusations being hurled in her direction, Ireland kept the tone of her tweets friendly.

"Great for people 2B honest. Helps me learn & grow," she wrote.

Still, she felt it necessary to clear up one question that seemed to be on everyone's minds: what was she on?

"No Red Bull or chemicals...just J.O.Y.!" she revealed.

In fact, Ireland attributed all her strange behavior to "J.O.Y."

"So many mis understood that the J.O.Y. was being invited 2 co host. Grateful to all," she wrote.

And at last night's Governor's Ball after the show, Ireland tweeted a general message to the public, thanking them for their kindness, and, "for those of you who were tough, thanks for helping me grow."

Kathy Ireland acted as one of ABC's red carpet coorespondents at the Academy Awards.
