According to People, the controversial performer commemorated the huge milestone with a number of activities.

Cyrus kicked off her born day by relaxing with her four dogs. The starlet even tweeted a picture of her snuggling with the canines, captioned "All I could want on my birthday."

But playing with her four-legged friends was just the beginning.

The "We Can't Stop" had dyed her eyebrows back to brown on Friday after bleaching them blonde earlier this week. The star had attracted a lot of attention and made headlines for the incredible beauty move.

Unfortunately, the former Disney darling didn't start her birthday weekend with a bang. Cyrus' home was burglarized on Friday afternoon, but she wasn't home at the time.

The Los Angeles Police Department told E! News that a victim reported that property was missing.

But despite the incident, Cyrus still is enjoying life. The pixie-cut songbird recently said that she was much happier after splitting with Hemsworth, who she was in a relationship with for three years.

Whether single or taken, Cyrus is known for causing controversy and over-the-top antics. Shocked and surprised that she toned down her behavior for her celebratory weekend? Tell us your thoughts with a note below!
