GMA stars Robin Roberts, George Stephanopoulos and Michael Strahan absent from colleague Will Ganss' wedding: 'People are whispering'

A host of ABC names showed up in force for Good Morning America reporter Will Ganss' 'wedding of the century' – but the show's three biggest stars were nowhere to be seen, the Daily Mail can reveal. 

Robin Roberts, George Stephanopoulos and Michael Strahan were noticeably absent from the joyous celebration as Ganss, 34, tied the knot with his partner, Jason Sparks, in the Big Apple last weekend, sources claimed.

'We would have expected one of the three. When one anchor can't make it, nobody thinks anything of it,' one insider told the Daily Mail. 

'When Robin, George and Michael all don't show up, people notice.' 

Other members of the extended GMA family were present for the lavish nuptials held at the Angel Orensanz Center in Manhattan's Lower East Side – with some affectionately dubbing it the 'wedding of the century.'  

New GMA Saturday co-anchor Rhiannon Ally, co-anchor Whit Johnson, ABC News correspondent Andrea Fujii and The View co-host Sara Haines were all front and center among the 155 guests. 

ABC correspondent Gio Benitez was there, too, flanked by his husband, Tommy DiDario.

The network colleagues, for their part, flooded social media with photos and videos of Ganss and Sparks' loved-up celebrations. 

But it only made the absence of GMA's three biggest names more noticeable.  

'Jason and I both come from big families, which meant we weren't able to invite everyone from work, including the anchors,' Ganss told the Daily Mail. 

'Robin, George, and Michael have each congratulated us since the big day. They are — and have always been — supportive of me, and I'm not the only one at GMA who feels that way!'  

None of the sources suggested that Roberts, Stephanopoulos and Strahan deliberately skipped the wedding. 

'That's what people are whispering about.' 

'There are Robin, George and Michael - and then there is everybody else,' the insider said.

'That is absolutely how it feels. They are the stars. They are treated differently, they have enormous power, and everyone is expected to show up for them.' 

Sources said the correspondents and junior staffers all understand that birthdays, weddings, farewell parties and celebrations aren't just social occasions – they're part of being a team. 

'If Robin has something important, people show up. If George has something important, people show up. If Michael has something important, people show up,' the first source said. 

'That support travels upward very quickly. People notice when it doesn't travel back down.' 

An insider, though, added: 'This team shows up for each other time and again often in private and off-camera ways—anyone actually close to them knows that.'

Robin, George ad Michael celebrated the newlyweds on on GMA Wednesday with Ganss on the air. 

Ganss got engaged to his creative director beau last summer with a Taylor Swift-inspired proposal. 

The Emmy Award-winning journalist, who is a proud Swiftie, shared news of the engagement on Instagram – complete with a sign reading: 'He knelt to the ground and pulled out a ring.'

Months later, Ganss shared a photo of himself posing alongside Swift as the pair both flashed their engagement rings. 

'Congrats, girl. We both got engaged to hot Libras this year,' he captioned the snap.
