Vanessa just celebrated her 23rd birthday last week!

Younger sister Stella wrote on her Instagram wall, “”Today is my beautiful sisters birthday. She is truly the only person I can trust 110% she has been there for me through everything. She’s seen me at my worst and my best and she never judges me for my mistakes. I wouldn’t be where I am today without her. She keeps me sane and INSANE at the same time(; hehe I love you nessa. I couldn’t ask for a better best friend/sister than you. #happy23rdbirthdayvanessa xo ❤”
