AceShowbiz - Britney Spears is "back already" on Instagram. Having been absent from the social media platform for a week, the "Toxic" hitmaker finally announced her return because she "couldn't stay away" from it too long.

In the accompanying message, she wrote, "Sorry I like long hair to twirl ... so this is me after vacuuming my living room with this bomb new glade Hawaiian breeze carpet cleaner !!!!! Holy hell it's great .... my living room smells so nice to WAKE UP to !!!!!"

"This song by Lenny Kravitz is a fun one to dance to ... of course my favorite lyric is I WAS BORN !!!! GOD BLESS YOU ALL and don't forget to stay grateful and say your prayers folks !!!!!" the pop star added. "Pssss my red dye came out in the shower and it looked like a crime scene !!!! Pssss ok ... I'm taking myself very seriously in this dance !!!!!!!"

Britney deactivated her Instagram account after announcing her engagement to her longtime partner, Sam Asghari. At that time, she informed her fans on Twitter, "Don't worry folks... just taking a little break from social media to celebrate my engagement!!!! I'll be back soon."

Sam will become Britney's third husband. The older sister of Jamie Lynn Spears was previously married to rapper Kevin Federline, with whom she shares two sons together. She was also married to Jason Allen Alexander for 55 hours in 2004.
