Ashley Tisdale slams body shamers: 'I'm not pregnant, I'm just happy'

Don't mess with Ashley Tisdale.

The former "High School Musical" star took down a Twitter troll who criticized her appearance at the Elton John AIDS Foundation's Oscars viewing party in the most epic way possible.

The 31-year-old actress looked absolutely gorgeous in a purple gown that showed off her curvaceous figure, but it seems at least one person on Twitter had something mean to say about her outfit. Of course, she wasn't going to let the rude remark slide.

"The pressure to [be] perfect is a struggle," she wrote on Twitter. "No I'm not pregnant, I'm just happy and haven't been strict on my diet, but thanks for the reminder."

Ashley is totally loving the skin she's in and we LOVE her for it!

The blonde beauty, who describes herself as quite an early riser, recently revealed to AOL.com how she gives her body a little TLC in the morning:

"I like to work out every morning," Tisdale said while talking about her partnership with Olay's DUO."I do kickboxing and sometimes yoga or Pilates."

She celebrated the launch of the DUO body cleanser at a Daybreaker party in Los Angeles last month.

She follows her workout with a filling vegan smoothie and a little meditation before hopping into the shower.

And after a productive morning before most people have even gotten out of bed, you can probably find Tisdale working on something for her YouTube channel, which she has recently relaunched. She teamed up with former co-star and gal pal Vanessa Hudgens in mid-January for an epic duet to Elle King's chart-topping hit "Ex's & Oh's."

"We realized we had never sang a song together -- which is crazy to think about. We were always so upset in [the 'High School Musical'] movies that we never got to collaborate."

It has gone viral since its release last month with 17.2 million views and counting -- who knew the former on-screen rivals would make such good music together?!

The YouTube personality also shares her insight on other topics, including beauty and Q&A sessions. Her latest video shows fans how to recreate her stunning look at Elton John's Oscars party.
