Adele has been quite secretive about her newborn son -- so much so that she has not registered him with the UK authorities and now faces a $1,600 fine. 
Huffington Post UK reports that singer has failed to file the necessary registration paperwork for her son within 42 days of his birth. Adele may soon hear from the authorities about the matter, the report said.
"Cops are hardly going to be banging on their door tomorrow and it's probably just an oversight on their part," a source revealed to the Sun.
According to the source, it is common for new parents to forget to register their babies within the initial deadline; however, they are responsible for doing so at some point.
"Most parents register their baby within a couple of weeks because it's a nice thing to do -- and because there's a maximum fine of £1,000 if they don't. There's loads of reasons why parents are late and millions of couples don't bother for ages."
According to Mstar News, the singer will likely not face any immediate legal action, but will receive some warning letters. If the baby's birth information is not filed to the registrar with three months, she will then be required to pay the fine. 
Little is known about the child, born Oct. 19 to the singer and her boyfriend, Simon Konecki, not even his name.
Mstar News notes this will force Adele to release official details about the baby. 
Following the boy's birth, the singer and her son were the target of Internet bullying via social media networks such as Twitter that included death threats, some reports said.
