Leann Rimes is furious she wasn't notified about her stepson's hospitalisation.
The 'Can't Fight the Moonlight' singer and her husband Eddie Cibrian only learned 10-year-old Mason - his eldest child with ex-wife Brandi Glanville - had been taken to hospital yesterday (30.03.14) after a friend read the news online.
She tweeted: !Got a text from a friend at 4:30am asking if mason was ok. THANK GOD! Mason just called Eddie himself!! It's been a panicked morning not knowing anything and mason being all the way across the US. Relived to know he's ok. (sic)''
However, the 31-year-old star - who has a difficult relationship with Brandi - went on to admit it initially may not have been easy for the reality TV star to get in touch with his former spouse.
Quizzed on their attempts to get in touch with Brandi, she admitted: ''he unblocked his number & called her at least 5 times and mason has a cell (sic)''
And when a twitter follower questioned why they had blocked Brandi's number, she accused her of sending ''horrible, evil'' text messages.
She responded: ''get horrible, evil texts at all hrs of the night and maybe you'd think differently god bless you (sic)''
Later in the evening, LeAnn admitted she shouldn't have made her grievance public.
When a follower suggested she should have kept the dispute ''off twitter for one'', she replied: ''you're right, I could have handled my side differently. Emotions took over Relieved he is ok Still don't agree w/ what happened (sic)''
And she then added: ''Hope you all have a nice Sunday night. Tmrw is a new day! Here's to positive vibes for a great start to the week.(sic)''
Brandy - who also has six-year-old Jake with Eddie - had revealed on twitter that Mason had been taken to hospital while in New York, where she has been busy with promotional appearances.
She wrote on Twitter: ''8 hours in the ER this trip to NYC Mason will never forget! 1st trip in an ambulance! All will be fine (sic)''.
The novel's author saw a cut of the film and loved each of the changes the movie's director had made.
