Katherine Schwarzenegger follows the footsteps of her mother Maria Shriver who's an award-winning journalist. "I am so happy to announce the launch of my new lifestyle website!" she tweeted. "Check it out and let me know what you think! Xo"

The 23-year-old entrepreneur was flooded with congratulatory messages from her family and friends. "My daughter @KSchwarzenegger's website went live today," her proud mother wrote. "It's beautiful, interesting & inspiring...just like her."

Younger brother Patrick Schwarzenegger, who recently made headlines for throwing a drunken fit during a night of clubbing, gave her a shout-out, and so did her celebrity friend Emma Roberts. The "Scream 4" actress gushed, "I love it. Congrats xo."

Katherine will offer style advice and cover health topics. "I also have a whole section dedicated to the tastemakers/experts in my life, so you'll get to hear from my fabulous friends, family and colleagues as well!" the oldest daughter of Arnold Schwarzenegger added.
