The 'All About That Bass' hitmaker has gushed over her friend's whirlwind romance with the 'Saturday Night Live' star, and revealed she is delighted about news of their engagement.

Speaking to 'Entertainment Tonight', she said: "I'm so happy for them. They are the cutest thing of all time!"

Although Meghan hasn't been able to catch up with the 'No Tears Left To Cry' singer since the engagement was revealed to the world, she admitted she noticed a ring on her finger during a recent live performance.

Ariana was on stage at the iHeartRadio Wango Tango event earlier this month, and it appears she couldn't hide the rock during her set.

Meghan added: "I saw that! And my mom texted me like, 'Yo, does anyone want to talk about this?' "

Her comments come after Pete, 24, confirmed the recent rumours that he had proposed to the 'No Tears Left To Cry' hitmaker, also 24.

'Tonight Show' host Jimmy Fallon joked: "Now, you know, that you didn't have to get engaged to Ariana Grande to come on our show."

His guest replied: "But I did though. I feel like I won a contest. I'm f**cking lit, Jimmy. It's so lit."

However, not everyone has reaction so well to the news - with Pete's friend Seth Rogen taking a cheeky dig at their very public displays of affection.

Pete seemingly couldn't get enough of his partner as he spotted a bikini picture she'd uploaded to the social media platform, and commented: "What the actual f**k"

Responding to her man - and his heart eyes emoji - Ariana said "I love you", only for him to try and one-up her as he wrote: "I love u more tho (sic)"

Seth had clearly had enough of the public exchange, and he took the chance to bring the couple down to earth with a tongue-in-cheek remark.

He simply replied: "Guys seriously."
