The news comes three months after Bobbi, who is Bobby’s daughter with Whitney Houston, was found unresponsive in her Atlanta home.
After being rushed to hospital, Bobbi was put into a medically-induced coma, but her father has now hinted that she’s showing signs of better health.
“Bobbi is awake. She's watching me,” he told the audience at Dallas’s Verizon Theatre.
Since Bobbi’s hospitalisation, her family have made very few comments on the 22-year-old’s health.
Back in February, her aunt Leolah Brown, Bobby’s sister, rubbished reports that the Brown family needed to decide whether to switch off the life-support machine.
“So many signs that she will be ok, despite what people are saying over the internet, Krissy is fine," she told Fox news. “She’s opening her eyes and there’s a few more things that she’s doing.
“Krissy is doing well right now.”
Bobbi Kristina was discovered in her bathtub at around 10.30am on 31 January, according to reports from a local radio station.
Police in Atlanta later confirmed that they were launching a criminal investigation into what left Bobbi Kristina submerged for up to 18 minutes in a foot of water at her home in Roswell, Georgia.
