Sinéad O'Connor has become a grandmother for the first time.
The 48-year-old singer's son Jake welcomed a little boy on Friday with his girlfriend. Sinéad was quick to update her fans of the happy news, taking to her Facebook page to share her delight.
'Don't mess with abuelita. (sic)' she wrote alongside a cartoon which spelled out 'It's a Boy'.
Sinéad has four children and Jake is the eldest, from her first marriage to music producer John Reynolds. The Nothing Compares 2 U singer has been married a further three times, most recently to Irish therapist Barry Herridge, who she met on the Internet.
Sinéad had posted on Thursday that her son's partner had gone into labour.
'OMG! Am literally hours away from the greatest dream of my life coming true! #Granny! (sic)' she wrote. 'This for Lia and Jake and their little angel, who flew about with me in Vegas last week as I was singing the Foggy Dew.'
Sinéad first confirmed the news of her impending grandparent duties in March on the social networking site. However she had to quickly clarify that it wasn't her 18-year-old daughter who was expecting, but Jake.
'It's my 27-year-old son Jake and his beautiful girlfriend, Lia! Am so delighted!!! Always wanted to be a granny. In fact that's the only reason I had kids (joking). Baby will be arriving in July.(sic)' she wrote.
Sinéad is a prolific user of Facebook, and earlier this week she took to the site to launch a bitter tirade against Rolling Stone magazine, which had put reality star Kim Kardashian on the front cover of its latest issue.
'What is this **** doing on the cover of Rolling Stone? Music has officially died. Who knew it would be Rolling Stone that murdered it? (sic)' she raged.
