The 23-year-old celebrated her final night out as a single girl on Wednesday evening (September 5).
However, the model and new mother has admitted that her night out with her girlfriends was a lot tamer than most other hen nights, and that she was home by 11pm because infant daughter Astala has left her feeling exhausted.
Geldof posted a picture of herself online, dressed in hen night bride's attire, which included a veil that had fake penises on it.
She also said: "Back home after my hen night at 11 as so exhausted from being woken up at 6am by baby this morning.
"It was just a little dinner at a sushi restaurant with the bridesmaids and a few close friends, but was nice to see everyone!
"I was given all manner of weird penis themed items in classic hen do style though so at least we did that part right even if the wild partying and male strippers were sadly absent!! (sic)"
However, during the evening, Geldof also tweeted: "Playing pin the penis on the gross ripped guy. Great."
