"About to cut my hair," she tweeted. "Ah. New hair do."
Soon after she showed off her stylish new cut on Instagram and wrote, "Short hair don't care." In another shot with her hairstylist, Spears marveled in a caption, "Still can't believe we did this!"
The younger sister of Britney Spears happily announced on Twitter March 2 that she was engaged to 30-year-old Watson after three years of dating. The former Nickelodeon star was previously engaged to Casey Aldridge, the father of her 4-year-old daughter, Maddie, before their 2010 split.
On March 24, Spears shared an adorable photo of her daughter helping her put makeup on. "Makeover day for Maddie and me," she tweeted. "Oh boy. Little moments. Blessed."
Later, the mother-daughter duo enjoyed a little bathroom dance party. "Jamming out after bath time to Rihanna," she captioned a picture of them posing together in a mirror. "Bright like a diamond."
