Jack Osbourne has described the "instant love" he felt for his new baby daughter.

The star, whose fiancee Lisa Stelly gave birth to baby Pearl two weeks ago, admitted he needed "time" to get used to the prospect of becoming a father.

The 25-year-old told Hello! Magazine:

The couple, who will marry later this year, had been together for three months when they discovered Lisa was pregnant.
