Singer Sonna Rae added: ‘You’re Will Smith! You can be in whatever shape you want,’ while meme creator Tank Sinatra said: ‘Let me be real with you. You’re 52. You look great.’
It comes after Will’s daughter Willow Smith recently revealed she is polyamorous on a recent episode of Red Table Talk.
The 20-year-old made the admission while speaking to her mother Jada Pinkett Smith and her grandmother Adrienne Banfield-Norris.
She explained: ‘With polyamory, I feel like the main foundation is the freedom to be able to create a relationship style that works for you and not just stepping into monogamy because that’s what everyone around you says is the right thing to do.’

‘So I was like, how can I structure the way that I approach relationships with that in mind? Also, doing research into polyamory, the main reasons why monogamous relationships – or why marriage – why divorces happen is infidelity.’
Willow – who practices ethical non-monogamy, meaning that all partners give consent to being polyamorous – was met with resistance from her grandmother who said: ‘For somebody like me, it feels like it’s really all just centered around sex.’
The star then gave her ‘Gammy’ an example of a couple who might have opposite appetites for sex.
She said: ‘Are you gonna be the person to say, you know: “Just because I don’t have these needs, you can’t have them either?”‘

‘And so that’s kind of one of the reasons why I actually was interested in poly because I was introduced to it through kind of a nonsexual lens.
‘In my friend group, I’m the only polyamorous person, and I have the least sex out of all of my friends.’
Willow – who said the ‘history of marriage really irks me’ – found a more open, compassionate listener in her mother Jada.
‘I’m okay with whatever you do,’ Jada said. ‘When you were like, “Hey, this is my get down.” I was like, “I totally get it.”

‘Wanting to set up your life in a way that you can have what it is that you want, I think anything goes as long as the intentions are clear.’
Willow’s ‘coming out’ was not a revelation as she already confessed she was bisexual and polyfidelitous (a form of non-monogamy) two years ago on her weekly Facebook Watch series.
‘I love men and women equally and so I would definitely want one man, one woman,’ the Calabasas native said at the time.
Resistance: Willow was met with resistance from her grandmother Adrienne Banfield-Norris (left) but her mother Jada was more understanding
‘I feel like I could be polyfidelitous with those two people. I’m not the kind of person that is constantly looking for new sexual experiences.
‘I focus a lot on the emotional connection and I feel like if I were to find two people of the different genders that I really connected with and we had a romantic and sexual connection, I don’t feel like I would feel the need to try to go find more.’
Since 2017, Willow has been in what appears to be a monogamous relationship with Tyler Cole, whom she met through her big brother Jaden.
