American singer and actress Miley Cyrus celebrates her 20th birthday on 23 November.

Born to country singer and actor Billy Ray Cyrus and his wife Leticia Tish Cyrus, she was named Destiny Hope Cyrus. However, she was soon nicknamed Miley because, as a little girl, she was forever cheerful and smiling; Miley comes from the word "smiley".

The excited star tweeted: "2 days till my birrrrfdayyyyy! if I don't get atleast one big booty hoe my friends are officially not my friends anymore."

The young birthday girl's family was the first to wish her on the day. The occasion was celebrated in New York City, where her father, mother, sisters Noah and Brandi and brother Braison met at the Ambassador Theater. According to a report in People, the entire family went backstage to be with Billy Ray, who is playing Billy Flynn in Chicago on Broadway.

"The whole family had a great time," a source told the magazine.

On a personal front, 2012 has been a good year for Cyrus. The Can't Be Tamed singer announced her engagement to actor Liam Hemsworth. The couple may have had a turbulent relationship in the past, since they met while filming The Last Song in 2009, but the 3.5-carat diamond ring on Cyrus' finger is proof the Hunger Games star and his beau are serious about their future together.

Meanwhile, the father of the bride-to-be couldn't be more supportive.

"The main thing for me is that both of them are happy," he was quoted as saying recently, "Miley's worked really hard, and I'm enjoying right now seeing her so happy."

As for the birthday girl, she said she was looking forward to being married and would probably take a break from work to enjoy that stage of her life.

"I am married in my heart and my mind. I do everything that I would be if I had the paper, but I want to take the time to actually enjoy it," she was quoted as saying.

Finally, rumours have suggested Cyrus is planning three ceremonies, which she denied.

"I didn't realize how much there was to do until I got a wedding planning book. I don't care what color the napkins are. I don't want to get too caught up in the little moments," she said on The Ellen DeGeneres Show, "That's my day, and whatever I want on that day will be about me and that moment."
