She's certainly had an eventful decade so we can see why Sarah Harding might've wanted to the round it off with a bang, but the Girls Aloud star instead made the far more sensible decision to have a quiet one. Well, she had only just left rehab.
Talking to the Mirror, a source explained:
"Sarah has had a tough year but she is a strong girl who is back on the mend. She has just left a rehab facility and did not feel ready to fly back to London to party - and she had to say no to people flying over to see her as well.
"She is using the time to recuperate and reflect by herself. It just goes to show how far she has come and is determined to change her life for the better. Her 30th birthday was supposed to be a shindig (bash) to dwarf all others. She had also been looking forward to planning her wedding next year but now she is adapting to life as a single girl."
Meanwhile, her Girls Aloud bandmate Kimberley Walsh, who also recently hit 30, threw her own big party, which Sarah was initially meant to co-host. Demonstrating how much they missed her presence, Cheryl tweeted; "happy Birthday Harding.. Love you babe.. !!", while Nicola added; "It’s our girl’s big day.. Happy Birthday Sarah.. Love u."
Aw, we're sure that helped her get over any birthday blues.
