The cast of ‘This Is Us’ welcomed a celebrity guest on the Season 2 set when Fifth Harmony’s Ally Brooke stopped by for a Pearson family affair. See the photos!

More from This Is Us

It’s the Fifth Harmony collaboration the pop music world never saw coming, and suddenly the entirety of Top 40 radio is shaking. This Is Us opened its top-secret, super-confidential set to a celebrity visitor on Monday, proving that you can gain front and center access to spoilers if you come bearing cookies.

Fifth Harmony’s Ally Brooke dropped by the This Is Us set on the invitation of Chrissy Metz, and the adorable photos will make you insanely jealous. If only we were all one of the members of a chart-topping international pop group with the ability to spend the afternoon on the set of our favorite shows. Luckily, the Fifth Harmony singer captured the divine experience of being an honorary Pearson, from bringing the cast treats to scoring the ultimate family photo. Metz wants to take the 5H-This Is Us collab one step further and have Ally on the show. We have a feeling she’s down — and so are we. Whether she’s a guest star or guest visitor, Ally Brooke did This Is Us fans proud as she unabashedly fangirled over the cast in an adorable outpouring of snaps shared on Twitter. Check them out below!

Ally Brooke shared the single most frame-able photograph of all time, posing with (almost) the whole This Is Us family. If you could feel our envious pulse right now, it would feel just like a sledgehammer.

Chrissy Metz invited the Fifth Harmony singer back to the set, but this time, Ally Brooke could have the opportunity to act alongside the Emmy-nominated cast. Hey, it could work. Brooke could guest star as a singer friend of Rebecca or Kate’s, or perhaps Miguel’s granddaughter?

Brooke snagged the selfie of all selfies — apart from hers with Chris Sullivan and Chrissy Metz featuring an ace photobomb from Susan Kelechi Watson, of course. Who else can say they have a photo with Mandy Moore made up in modern-day Rebecca makeup?

And clearly, Ally Brooke made quite the impression on the cast, as Justin Hartley, Chris Sullivan, and Faithe Herman (who plays Beth and Randall’s daughter Annie) showed the singer — and her cookies! — some love on Twitter.

But it’s back to work (work work work work) for the Fifth Harmony star, who’s set to release her third album with the group on August 25, one month before the Season 2 premiere of This Is Us. Prior to what’s sure to be a whirlwind promotional blitz, Ally Brooke’s day as an unofficial Pearson was definitely worth it.
