Get ready for Olivia Wilde gone birthday wild.

The gorgeous Ms. Wilde turns 29 tomorrow.

"It's a big day tomorrow—a big day!" she just told me at the SXSW premiere of her movie Drinking Buddies. "It's the last year of my twenties."

Take a look at Olivia's engagement bling here!

So what's Olivia got planned?

"I am going to wreak havoc on the world," Wilde laughed. "The world will not be the same." Fiancé Jason Sudeikis will help her celebrate when they meet up tomorrow in Los Angeles.

Speaking of the husband and wife to be, Wilde said she has "no time to plan" the wedding. "Really no time," she said. "But I'm very lucky to be this busy."

And lucky to be in love.

"I'm so happy," she said. "There's nothing like it."
