Jack Osbourne thinks his baby daughter is ''advanced''.
The 'Haunted Highway' star says people should expect ''big things'' from little Pearl, his child with fiancee Lisa Stelly, because she has already begun reaching her milestones early.
He said: ''She rolled over for the first time yesterday, so we're pretty excited about that.
''So she's advanced. We read online most kids don't do it until 14 weeks, she did it at 10-and-a-half weeks ... Expect big things from Pearl Osbourne.''
Lisa is equally proud of Pearl's achievements, tweeting: ''Almost 11 weeks old and Pearl did her first roll over last night! And she did 2 this morning already! #proudmommy (sic)''
Jack, 26, recently revealed he had been diagnosed with multiple sclerosis (MS) shortly after Pearl's birth and though he admits the news was initially hard to take, he now knows his condition is ''manageable'' and says he has other priorities ahead of his medical problems.
He told 'Access Hollywood': ''I'm alright. I think when you get news like, 'You have MS,' it's a bit of a buzz kill, but when you do a bit of research into it, you realise it's quite manageable as long as you take care of yourself.
''Having a new baby is forcing me to just focus on that and work, so it takes the sting away a little bit.''
