The troubles of Londonderry singer Nadine Coyle seem set to continue in 2012 as her US dream business venture faces the threat of closure.

Singer Nadine Coyle bought the beach bar for her parents

The former Girls Aloud star, who saw her solo album flop last year, faces the new year amid threats that her Californian beachfront bar could be seized for non-payment of taxes.

The nightspot, Nadine’s Irish Mist, based at Sunset Beach, Orange County, owes close to $100,000 to the US taxman after it emerged no taxes have been paid during its existence.

The struggling Derry singer purchased the bar in 2008, granting a long-held wish of her parents, former Bogside residents Niall and Lillian Coyle.

And when it opened in time for St Patrick’s day in 2009 it received rave reviews.

In 2010 one local television station described the venue, run by Niall and which hosts traditional and contemporary music nights, as the best Irish restaurant in the LA area.

However, public records in Orange County have revealed that since its purchase no property tax has been paid.

For the year 2011/2012 the tax owed is over $18,000, with the first instalment due last month.

The second payment is due next month.

The records show a further amount of more than $70,000 is owed, including some $19,000 in fines.

Under local laws, a property is subject to sale for non-payment of taxes after five years.

Niall Coyle, the sole agent for Nadine’s Irish Mist’s parent company Charnarae, faces further troubles after its business licence was suspended for failing to supply a statement of information including documents detailing company address, directors and the nature of the business.

With its licence suspended now, though, it cannot legally operate and technically is required to close its doors, preventing it from collecting any payments due from third parties or engaging in business transactions.

The Coyles’ ailing business affairs appear to have affected their luxury lifestyle too. They have moved from the $7000-a-month rental property they acquired when they arrived in the US to a much more modest rented four-bedroom house.
