"Yay!!! Thank you every one! Getting my little self trending on the twitter!! Great bday pressie. Love love love," she wrote.

The expectant starlet is also indluging her sweet tooth for her special day.

"Thanks for all the early bday wishes guys!think I'm going to treat myself 2 an early bday pinkberry!mango&mochi 4life!" she tweeted late last night.

Having a bun in the oven on your birthday is the perfect excuse to eat whatever you want. Happy b-day, Hil!
