Maggie Gyllenhaal named her newborn daughter Gloria after falling in love with rocker Patti Smith's rendition of the Van Morrison classic.
The actress and her actor husband, Peter Sarsgaard, welcomed their second girl in April, and Gyllenhaal says they had the tot's name picked out long before she even got pregnant.
She tells Jimmy Fallon, "We thought of her name when we were at this concert that Patti Smith played at and she played 'Gloria,' and it was a couple of years ago and we thought, 'We'll name our daughter that one day.'"

But the actress isn't a fan of all covers of the track, which was originally recorded by Van Morrison's band Them.
She says, "My husband played me The Doors' version of 'Gloria' two days after my daughter was born and it was so dirty, I couldn't handle it. It was a super, super dirty version! Van Morison has an awesome version, which is the one Patti Smith is covering, but she does hers totally her own (way)."
Gyllenhaal and Sarsgaard, who wed in 2009, are also parents to daughter Ramona, 5.
