New record: Longest fingernails on a pair of hands (female) Diana Armstrong (USA) has been growing her fingernails for over 25 years and has vowed to never cut them again...https://t.co/c8HTr4oDmdpic.twitter.com/7wnElFOn7M

The woman named's Diana Armstrong's fingernails measure about (1,306.58 cm) 42-feet 10.4 Inches long, GWR said, adding that the record was set in March this year.

Her right thumbnail, which measures 138.94 cm (4 ft 6.7 in), is the longest of all her nails whereas her left pinky fingernail - smallest of her nails - is 109.2 cm (3 ft 7 in) long.

Ms Armstrong last used a nail clipper back in 1997. The reason for not using it after that is a heartbreaking accident that changed her family.

Getting her children out of bed and heading to the grocery store to buy food for her family was how Diana had begun her day as usual that year, the GWR release said.

While shopping, Ms Armstrong got a panicked call from her youngest daughter. "At the store, my baby daughter called me and told me 'Ma, Tisha won't wake up'," she recalled. Aged just 16, her daughter Latisha died because of an asthma attack while sleeping.

"That was the worst day of my life," GWR quoted Ms Armstrong as saying. She used to get her nails done by Latisha every weekend.

"She was the only one who did my nails. She polished them and filed them for me," Ms Armstrong told GWR.

Over the years, Ms Armstrong's children tried convincing her to trim her fingernails. "My kids said 'Ma, you need to cut your nails.' I would tell them 'Mind your business."

Now that they have reached such extreme lengths, each of Ms Armstrong's nails take between four and five hours to paint.

The previous record for the longest fingernails on a pair of hands (female) was held by Ayanna Williams (also from the US) before she made the decision to cut them off. Ms Armstrong broke Ms Williams' record by an astonishing 573.03 cm (18 ft 8 inches).
