Lady Gaga made an impromptu appearance at a saloon bar in Texas on Saturday (July 24).

The US singer thrilled locals at The Round-Up Saloon in Dallas, which was the scene of one of her earliest performances.

Although she didn't sing, Lady Gaga led drinkers in an energetic sing-along to her hits 'Just Dance' and 'Alejandro'.

She was accompanied to the bar by an entourage of 15 people, which included her mother, according to a report on US website The Count.

The singer was also spotted ordering drinks at the bar for her guests.
