Robbie Williams gets real about ONE thing that drains him

Robbie Williams, global pop icon and a heartthrob who is best known for his powerhouse vocals, has recently got real about one thing that takes a serious toll on his mental health.

The 51-year-old star took to Instagram to reveal how being asked for selfies by fans can make him feel anxious and uncomfortable. He even shared a few stories from a recent flight in America, showing just how overwhelming things gets sometimes for him.

While voicing his concerns, Robbie captioned: "I'm sat on a domestic flight, going across America.

"I've had three interactions so far with fellow passengers. One of them handed me a lovely note -kind words about my documentary - and then asked for a photo.

"I wrote a note back. I explained I'd been up since 4:30 a.m., had two hours' sleep, and wrangled four kids through the airport. I've got bags under my eyes and I'm dealing with anxiety. I explained that if they came and took a photo with me, my anxiety would spike - because then the whole cabin would start wondering who I am. And I'm not famous here," he explained.

The chart-topping artist went on writing, "That kind of attention would only pile more anxiety on top of my already-thriving 'being outside' unease. I didn't say no I wrote back, offered the letter, and said: 'Lots of people have photos with me, but no one's got one of these.'

"Then a lovely steward came down and said there was a man at the back of the plane who was a big fan of 'Rock DJ' and wondered if he could come take a photo. I wrote a similar note on the back of my plane ticket and said that when we land, I'll be trying to shepherd four children. Again, I didn't say no. I just hoped the note might be enough.

"As I was writing that one, another passenger walked up and just asked outright for a photo. I obliged," the Feel hitmaker added.

However, Robbie Williams now see taking selfies with fans as a way to make them happy, though he didn’t always feel that way.
