Sinead O'Connor: See Her Las Vegas Wedding Photos!

Sinead O'Connor has followed in the footsteps of Britney Spears -- and tied the knot last night at the infamous Little White Wedding Chapel in Las Vegas.

The bald singer celebrated her 45th birthday yesterday by getting married to boyfriend of a very short time, Barry Herridge, while wearing a pink dress in the back of a pink Cadillac. The groom also wore pink.

The "Nothing Compares 2 U" singer showed off her many tattoos in a low-cut gown during the quickie 10-minute ceremony and posed for photos outside the Chapel afterwards.

The Chapel is the same place Britney married Jason Alexander at back in 2004. Hopefully Sinead and Barry's relationship lasts a little longer; Britney and Jason had their marriage annulled after 55 hours.

Congrats to the happy couple!
