Single Lady? The former Destiny's Child star was wishing a friend happy birthday in the video and inadvertently showed off the sparkler to the camera

Tim popped the big question to the 33-year-old X Factor USA judge sometime last week, according to celebrity website Bossip.com.
Kelly is seen waving to the camera, and inadvertently revealing the ring on her wedding finger, in an Instagram video Tim posted in which she wishes a friend a happy birthday.
Earlier this month there were reports the pair had got matching tattoos on their wedding fingers, which sparked speculation they were planning to marry.

In September MediaTakeout went as far to claim Kelly and Tim had actually secretly wed earlier this year in February - but these reports were never confirmed.
A source told the website at the time: 'Kelly and Tim have been together for years, and decided to get married.
'Kelly wants to keep her sexy singer image alive, so she's keeping everything a secret. Most people didn't even know she had a boyfriend.'

Indeed Kelly has kept her relationship with Tim very low profile and they avoid posing together at public events.
In contrast, Kelly's former Destiny's Child bandmate and childhood friend Beyonce - who married rapper Jay-Z in 2008 - has one of the most high profile relationships in the entertainment industry.
MailOnline has contacted Kelly's representatives and awaits comment.
