There is someone huge missing from Ross and Emily's wedding.

Ross Gellar and marriage is as timeless a pairing as spaghetti and meatballs. The two just go together seamlessly.

But Friends super fans have just pointed out a huge glaring problem from Ross’ wedding to his short-lived English love, Emily Waltham. And that’s a key member of the crew being missing in action.

The 1998 episode, titled ‘The One With Ross’s Wedding’ had his sister Monica Gellar present, as well as friends Joey Tribbiani and Chandler Bing.

Rachel Green made her famed wedding-stopping entry in the midst of the ceremony and Phoebe Buffet was at home in New York pregnant with her half-brother's triplets.

Ross's parents were there alongside other friends from New York - all of whom watched on as he said the wrong woman's name during the vows - but where, oh where, was his beloved son Ben?

According to Metro, the hit show's producers actually forgot to invite Ben...

Awkward.

So very, very awkward.

Ben, who was from Ross's first marriage to Carol, was featured regularly throughout the show's 10 seasons but remained absent from his father's wedding. To be fair, he also missed Ross and Rachel's Vegas wedding as well, so it did go on to become a theme.
