Susanna looked typically stylish in a long-sleeved and collared burgundy dress as she announced the top news of the day.
But attention was drawn to her left hand, where she appeared to be wearing a chunky gold ring on her fourth finger.
One person wrote: ‘Is Susanna Reid wearing a wedding ring? When did she get married?’
While another echoed: ‘Is @susannareid100 wearing a sparkler on her wedding finger?’
Susanna has never been married previously, but was in relationship with sports journalist Dominic Cotton, 55, for 16 years.
The couple share sons Sam, 20, Finn, 19, and Jack, 18, but announced their split in 2014.
Discussing her decision to not tie the knot with Dominic, she said on GMB in 2021: ‘It was a personal choice.
‘It’s a bit of an old-fashioned idea that children are “illegitimate” if you’re not married. Children are legitimate, whether you’re married or not.’
Susanna went on to find love with Crystal Palace chairman Steve Parish, 58, first going public in November 2018 when they were pictured at a Crystal Palace v Chelsea match.
A friend told The Sun at the time: ‘They have known each other for several years through their connections to Palace.’
They split just months later in April 2019 following a nine month relationship, as Susanna insisted they would remain good friends.
Piers Morgan highlighted the split at the time during a GMB appearance, asking her: ‘Are you single again? You are aren’t you?’
An upbeat Susanna replied: ‘Yep. Let’s not dwell. I’m fine, we’re fine, we’re very good friends. We were at the match on Saturday.
‘I know one of the things you’re most devastated with my split, is the fact you will no longer have access to the wine cellar,’ she added before presenting her friend with three bottles of Crystal Palace wine to ‘commemorate the epic occasion of Palace beating Arsenal.’
‘Steve let’s make this clear, you’ve broken up with Susanna and not me,’ Piers joked. ‘Your wine cellar remains a very important part of my life.’
‘I think it’s nice that you guys went to the football… these things happen right,’ he continued. ‘They do,’ agreed Susanna. ‘And we remain friends. Very good friends.’
The pair have sparked rumours that they have rekindled their romance several times in the years since,.
In August 2020, they were seen hugging on a night out together in Soho, with a source saying: ‘They looked totally into each other. If ever it was in doubt whether they were an item again, this shows they are.
‘Steve had his arms protectively around Susanna and tenderly planted a kiss on her head at one point before they flagged a cab.’
However, their relationship has never been confirmed and Susanna has expressed that she does not wish to ever get married.
While dating Steve, she previously told The Sun: ‘I’ve never wanted [marriage]. I’ve never fantasised about the big day. It was never my ambition to be married.
‘I’m very, very happy at the moment, but I don’t want to be married. No, no, no, I think the focus should be on the relationship.’
