As the big day arrived this year, Lisa marked the occasion with a tweet featuring her irreverent sense of humor that we all know and love. "Uh....oh," Lisa's tweet began, "Getting older."
Last year, Lisa celebrated her birthday by doing whatever she wanted. What that looked like was Lisa sipping tea in a ball gown with her adorable pets by her side.
There was also a pretty and pink party at PUMP thrown in her honor.
We can't wait to see how Lisa celebrates this year.
Until then, this video of Dorit Kemsley's son Jagger singing "Happy Birthday" is sure to melt your heart.
