The former Girls Next Door star is having a difficult time expressing her feelings about the Playboy mogul's death, taking to Twitter and Instagram to share photos of their many memories together.
"Thank you for all of your thoughts and condolences guys," she tweeted this morning. "Can't really put in to words how I really feel. It's easy to say he will be missed and how much I loved him. There's a lot more than that."
Kendra also took to Instagram to share a collection of photos from the memories together, including her wedding, introducing Hef to her son and spending time together at the mansion.
"Thank you Hef," she captioned the photos.
As you likely know, Kendra moved into the Playboy mansion at just 18 years old and began "dating" Hef shortly thereafter. She was one of Hef's three main girlfriends—including Bridget Marquardt and Holly Madison—who all starred on E!'s Girls Next Door together.
After Kendra and Hef split, the two remained close, even when the model moved on with Hank Baskett. In fact, Kendra held her wedding at the Playboy mansion and Hugh sat in the second row to support her.
Meanwhile, Kendra broke her silence on his passing Thursday morning, releasing the following statement to E! News: "Hef changed my life. He made me the person I am today. I couldn't be more thankful for our friendship and our time together. I will miss him so much but he will be in my heart forever."
