The Playboy mogul once again took to Twitter to express his feelings about the cancellation of his wedding to model Crystal Harris.
Hefner wrote: "It's the start of a new day, and a new week, and I'm happy to be single."
Last weekend, the 85-year-old admitted that he did not want really want to get married in the first place.
Hefner tweeted: "After all is said and done, staying single is probably the best. I think I just missed a bullet."
Hefner is reportedly seeing this year's Playboy 'Miss January' Anna Sophia Berglund, while former Playmates Karissa and Kristina Shannon have moved back into the Playboy mansion.
He tweeted about the twins earlier on Monday evening, saying: "The Shannon twins are staying in the Bunny House for a few weeks until they get their own apartment."
Harris revealed last week that she called off her nuptials because she was not the only woman in Hefner's life, stating that she did not feel comfortable marrying a man who was involved with other women.
