Married At First Sight's 2027 season is set to feature a significant shake-up with the addition of Love Island Australia star Zac Nunns as an intruder groom. Nunns married TikTok influencer Vanilla Milla on Monday in front of the original cast, a move producers hope will create compelling storylines and boost viewership.

Nunns, who gained prominence on Love Island Australia in 2023, brings with him a history of reality television drama. His best friend and Love Island co-star, Trent Woolman, served as his best man at the wedding ceremony. Insiders suggest Nunns is already generating conflict with existing cast members, with one couple reportedly leaving the wedding celebration after an argument.

A production insider described Nunns as "exactly the sort of personality producers know they can build stories around," citing his outspoken nature and willingness to engage with on-camera dynamics. His previous reality TV experience is seen by producers as an advantage, ensuring he will be comfortable with the filming process and contribute to storylines.

Nunns' arrival is expected to stir the pot at dinner parties, and producers anticipate he will readily share his opinions, influencing the group's overall dynamic. His 'bad boy' persona from Love Island is something he may lean into or aim to overcome, adding another layer of intrigue for viewers. The existing audience recognition from his previous show also creates an immediate curiosity factor regarding his intentions and potential for maturity.

Producers view Nunns' casting as a calculated risk, leveraging his familiarity with reality television and his existing fanbase. His past relationship with Love Island's Lucinda Strafford provides a potential redemption arc, allowing him to present himself as having learned from past experiences and now ready for a lasting commitment.

In a separate development, former MAFS groom Chris Nield was reportedly barred from attending Nunns' wedding. Production sources stated the decision was to prevent interaction between current and former cast members during filming, rather than any personal conflict between Nield and Nunns.

Meanwhile, MAFS expert John Aiken has cautioned viewers to expect an "extreme" season, heavily influenced by social media trends, particularly TikTok. Aiken noted that the show would tap into current dating debates prevalent online, suggesting a more intense dynamic among participants.

The upcoming season has already faced controversy with one groom exiting the experiment midway through filming under undisclosed circumstances. In response to off-camera incidents, Channel Nine and production company Endemol Shine Australia have implemented stricter rules. These include limiting participants to one alcoholic drink per dinner party and, in some cases, prohibiting alcohol in apartments to curb arguments that extend beyond filming.

These new regulations follow similar drug-testing measures introduced for the previous season after contestants violated curfew during a weekend off.
