Paris Hilton took a break from celebrating her birthday (her 30th!) to call in and chat with Ryan on his morning radio show today.
The heiress said her Moulin Rouge-themed party in L.A. earlier in the week was "amazing" and "so much fun."
But the conversation wasn't just about cake and candles.
Paris also opened up about her upcoming new show on Oxygen and how happy she is with her main squeeze Cy Waits, calling him "the best boyfriend on Earth."
