The 34-year-old took to Instagram (as per usual) this week to share a snap of some gorgeous flowers along with a personal note from One Big Happy producer Ellen.
"Have a great show, love Ellen & AVGP," it read, "PS: Don't tell the others but you're my favourite."
"Thanks Ellen. I knew that," Kells captioned the snap. But one little look at the comments below reveal that Ellen sent the same message to Kelly's One Big Happy co-star Elisha Cuthbert. #Lol.
"Hey! I got the same card!?!? Wait a minute?" wrote Elisha. Ah, these LA in-jokes are just too much. Our sides are splitting.
Earlier this month Kelly - who recently got engaged to bodybuilder and former gladiator beau David McIntosh - confirmed the news she'd landed a leading role in the NBC "multi-camera pilot."
The series, written by Liz Feldman and directed by Scott Ellis, will see Kelly playing a British girl called Prudence, described as "a sexy Mary Poppins", "a free spirit" and "wholly enchanting".
The flowers come as KB strikes a pose in an array of vintage-style swimsuits from her latest collection for high street retailer New Look. It's a line she's so proud of, she's already plastered it all over Instagram.
