I want to thank my kids, James, Inez, Betty, Olin, who are here.

According to Nameberry, Olin is a Swedish boys name meaning to inherit.

But that doesnt mean we definitely know the babys gender, of course.

Lively and Reynolds picked a gender-swapped moniker for their first daughter, James, remember.

But maybe Taylor Swift will give us all a hint in her next album.
