The sister of "Mob Wives" star Big Ang thought she was doing a good thing by creating a donation page for medical costs, but quickly had second thoughts ... and is now apologizing to Ang's fans.

Janine Detore says "Mob Wives" fans were reaching out and asking how and where they could make donations to help Ang cover bills for her throat cancer treatment. So, Janine created a GoFundMe page.

But after less than a day a fan wondered why a celeb was asking for money. Detore realized it was a good point. She tells us Ang and the fam can more than handle any expenses insurance doesn't cover -- so, she immediately disabled the page.

Detore says they only got about $150 during the few hours the page was active. She adds, Big Ang had no idea the page was ever up.

As for Ang's condition ... she's resting at home and doing very well -- but Janine says doctors are planning another surgery to remove her right lymph nodes ... as a precaution.

British singer Josh Cuthbert from the hit boy band Union J was in a violent car crash that was so bad it could have derailed the band.

Josh and Chloe were lucky, escaping with soft tissue injuries to their necks and some bruises. The ride is totaled.

FYI ... drivers are supposed to stay far enough behind the car in front of them so they can stop in time if the other driver pulls a bonehead move.

Union J is currently on a European tour with The Vamps. We're told the accident won't sandbag any of the upcoming shows. But turning's gonna be a bitch.

She goes on to say her mom, Andrea Finlay, was diagnosed after Taylor begged her to get a checkup. Taylor says, "She wanted you to know because your parents may be too busy juggling everything they’ve got going on to go to the doctor, and maybe you reminding them to go get checked for cancer could possibly lead to an early diagnosis and an easier battle."

She doesn't specify what kind of cancer it is ... or what the prognosis is for her mother, who is 57.
