Sinead O'Connor Gets a Marriage License in Las Vegas
The Irish singer, who also turns 45 on Thursday, applied for and received a marriage license Wednesday night.
O'Connor also posted photos on her website showing her and fiancé Barry Herridge en route from Dublin to Sin City for what she called "my absolute dream wedding ceremony."
She promises to post "a photo or two" as soon as possible after the ceremony, which was expected to take place on Thursday.
The "Nothing Compares 2 U" singer split from longtime friend and collaborator Steve Cooney in April.
