Married At First Sight: Elizabeth Sobinoff's 'groom' Seb Guilhaus without ring ...

Seb Guilhaus 'wed' repeat Married At First Sight bride Elizabeth 'Lizzie' Sobinoff during Monday night's episode.

And the couple may have already called it quits, with Seb spotted with what looked to be his ring on the wrong finger, just hours ahead of the episode airing.  

The 30-year-old former footy player failed to crack a smile as he stocked up on groceries at a supermarket in Sydney's Chatswood.

Seb showed off his muscular frame in a white T-shirt, which he paired with khaki shorts and white Converse sneakers.  

He slung a pair of dark aviator sunglasses on the neckline of his shirt, and listened to music while browsing the aisles.

Seb carried several grocery bags out of the store, drawing attention to what appeared to be his ring on the middle finger of his left hand.

Daily Mail Australia has reached out to Seb for comment in relation to the ring. 

The episode was filmed late last year, meaning it's possible Seb has already split from Lizzie, 28.

However, the pair appeared to be a great match, with Seb immediately smitten as he watched his bride walk towards him.
