Sinéad O’ Connor has got married in Las Vegas.

The Nothing Compares 2 U singer tied the knot yesterday, on her 45th birthday.

The star wed Barry Herridge in the back of a pink Cadillac in a drive-thru ceremony.

"She wanted to do the whole thing in a Cadillac. That was her thing," a source told People.

Sinéad wore a low cut pink dress that showed off her large tattoos. She arrived at the venue at around 7pm to fill out the paperwork before saying ‘I do’.

"It wasn't a traditional dress, but it wasn't a traditional wedding either," says the source. "She cried during the vows and had to wipe her eyes."

Barry wore a dark suit and pink shirt for the occasion.

After the short ceremony the couple lit candles in the reception while the staff at A Little White Wedding Chapel sang Happy Birthday to the bride.

This is the singer’s fourth marriage.

Her divorce from her third husband Steve Cooney was finalised in April of this year.

She has also been married to John Reynolds and Nicholas Sommerlad and has four children.

Sinéad met Barry after she revealed she was looking for a potential suitor in August.

She wrote about how determined she was to find a man on her blog. Her post caused controversy, as she admitted she was “desperate for sex…I am in the peak of my sexual prime and way too lovely to be living like a nun, and it's very depressing.”

Barry contacted the 45-year-old shortly after reading her blog via email and the pair quickly fell in love.
