“The X Factor UK” season 15 live shows are set to kick off in just a few days, we previously reported which Girls' team members are competing for the public vote with their mentor Simon Cowell and, we also discussed Louis Tomlinson’s emotional Judges’ Houses results for the Boys.

Who then, is Robbie Williams taking to the live shows for the Groups and which Overs is his lovely wife Ayda taking through with her? Overall, each judge is taking four acts to lives with them this season, which is one more than the standard three acts who advanced in prior seasons.

Adorable husband-and-wife newbie judges Robbie and Ayda Williams hosted their first Judges’ Houses performances at their sprawling mansion in Beverly Hills. Robbie is mentoring an eclectic mix of Groups this season. Perhaps the saddest loss came when he decided to eliminate newly-formed duo Panda and Burgandy. Though he was the one that originally put them together, he ultimately told the ladies they seemed more like individual singers than a well-blended group in their "Ain't No Mountain High Enough" performance. Their sunny personalities will be missed! Girl group Sweet Sense was also sent home that night.

In the end, Robbie advanced LMA choir for their incredible rendition of James Bay’s smash hit, “Hold Back the River.” He also advanced infectious teen duo A Star, reggae/R&B duo Misunderstood and newly formed boyband Vibe 5, who impressed with their cover of “Say You Won’t Let Go” by former “X Factor UK” champ James Arthur.

Meanwhile, Ayda has an incredibly strong category in the Overs as well. Comeback hopeful Janice Robinson staked a huge claim with her original song “Love is in the Atmosphere.” Rocker Giovanni Spano crushed his take on “Use Somebody” by Kings of Leon. Both acts went through along with Caribbean singer Olatunji Yearwood and emotional singer Danny Tetley, who may have delivered his series-best performance of “Over the Rainbow” to seal his spot.

In all, one of the 16 acts currently competing for the public’s vote will ultimately win “The X Factor UK” season 15 title and recording contract grand prize. It’s still too early to declare a frontrunner among all these talented hopefuls.
