It's that time of year again - Married at First Sight UK has returned to our screens with a brand-new lineup of brides and grooms.

For those who aren't familiar with the Channel 4 experiment, this reality TV show features singles who marry complete strangers, meeting them for the very first time at the end of the aisle.

Participants enter the process entirely blind, knowing nothing about their future spouse until their wedding day.

The latest series premiered yesterday (21 September) and the drama is already in full swing, with one bride's reaction being anything but love at first sight.

One of the initial couples featured on the show was 31-year-old recruitment consultant Sarah, paired by the experts with team building host Dean, also 31.

Upon first seeing his future wife, Dean expressed in a confessional: "She's smiling, she's looking at me, and I think this is the woman for me. It's off to a good start; the personality's there. I hope she's feeling the same way."

However, in her own confessional, Sarah's first impression of her future husband was rather harsh.

"No, I don't fancy Dean," she admitted, "I'm sorry."

Sarah continued: "Dean is such a lovely guy, but to be completely honest, I don't feel the urge to tear his clothes off."

Meanwhile, Sarah's friend Caitlin also commented during the MAFS UK episode: "Looks are very important to Sarah, and he is definitely not Sarah's type."

And if things weren't awkward enough, Dean decided to perform a rap for his new wife while they were still at the altar.

He awkwardly sang: "When I saw you in that dress today, you did more than take my breath away. All my fears alleviate, I know we're gonna be okay. I know we'll have hard times, it's true, but I'll never ever give up on you.

"You and me, plain to see, to the end of time, hopefully. Everybody sing with me. When I say wed, you say D."

Reflecting on the unexpected moment, Sarah later told the camera: "I'm feeling a bit overwhelmed. The rap is not something I envisioned, I have to say."

Understandably, viewers have taken to social media to share their opinions on the pairing, and many are disappointed that the couples seem to be 'fixating on looks.'

One Twitter user wrote: "MAFS p***es me off every year because why are they so fixated on looks. If you’re that bothered, find a man yourself #MAFSUK."

Another added: "Sarah 'my usual type isn’t working, I want something different, a nice guy, looks don’t matter' Experts 'here’s Dean' Sarah…. #MAFSUK."

A third agreed: "When I catch Sarah’s friends looking at Dean with disgust on their faces #MAFSUK."

"Why are they acting like Dean's an ogre at the end of the aisle #MAFSUK," added a fourth.

A fifth penned: "I know it happens every year, but Sarah has a terrible attitude for someone who’s only on this show because they’re tired of always going for bad boys #MAFSUK."
