Houston sang “Who Would Imagine a King” from The Preacher’s Wife. “[It’s] one of Krissy’s favorites,” a source tells People.com, “and is not in the show.”
Earlier in the week, mom and daughter “rented a beautiful boat and took a four-hour cruise all around Sydney Harbor with Krissy’s friends, the dancers and family members,” adds the source.
“That was the pre-birthday celebration. The cake at the concert was a complete surprise to Krissy. She had no idea!”
Happy Birthday, Bobbi Kristina!
