Lady Gaga made a random appearance last night (Mon. Jul 11) at Club Nevermind in Sydney, Australia.

The singer, who is in Sydney for a one-off performance at the Sydney Town Hall later this week, teased her Twitter followers earlier in the day by hinting at her appearance at the popular Australian gay club.

Gaga is also set to perform alongside Coldplay, Nicki Minaj, Jennfer Lopez, Alicia Keys and many others this fall at the I Heart Festival in Las Vegas. Check out a dozen or so pics of her performing in Sydney last night below:
