Amy, 23, had headed to the Hammersmith Apollo in London with her family to watch some stand-up when she spotted 24-year-old Tinie in the crowd.
The pair then posed for a picture together, which Amy shared with her fans on Twitter.
Alongside the photograph, the former Only Way Is Essex star said: "Guess who I bumped into? @TinieTempah, great show at the Apollo."
Amy wore her dark red hair in big bouncy curls for her night at the Apollo and dressed up in a pretty patterned top and statement purple necklace.
Tinie, meanwhile, opted for smart casual and wore a black T-shirt, brown leather jacket and, of course, his trademark black rimmed glasses.
For the best part of this week, Amy has been busy launching the Amy Childs Academy for budding spray tanners at the Olympia Beauty show in London's Olympia.
It's nice to see she was able to have a night off! Before heading out, Amy tweeted: "Off to the Hammersmith Apollo to watch some comedy acts with the family #banter #familytime."
