The Cowboys & Aliens star poked fun at the teenager when she saw a photograph of him out and about in chilly London topless, and urged the Baby singer to put a shirt on, but Bieber nation was far from happy with her motherly advice.
During an appearance in The Tonight Show with Jay Leno on Tuesday (12Mar13), the fun-loving star brushed off the drama and read out a few choice tweets she could actually air on Tv.
Wilde said, "I got a lot of interesting feedback from his fans... At first I thought they were being mean, but then I realised that it's just helpful advice.
"One of them was: 'Are you a lesbian or are you too old?' It's a question I had never asked myself before. I was wondering... 'Am I too old to be a lesbian, because I did just have a birthday, so I may have missed my window'."
Another tweet read: "B**tch, you're not his mother!"
Wilde added, "There's about 70,000 others but they are too many expletives."
