Selena Gomez will star in the first episode of 'Wizards Beyond Waverly Place'

Appearing on 'Jimmy Kimmel Live' - which was guest hosted by her 'Only Murders in the Building' co-star Martin Short - she said: "I'm so excited.

"It's basically something you know I don't know about your life, you don't know about my life. It's a show that means a lot to me."

The 74-year-old presenter replied: "I know it does. Because you started out in that show. And also you're appearing on it, too?"

Selena confirmed: "Yes. I will be in the first episode. I'm ex ecutive producing it. It brings me to tears because that is the beginning of where I started. And to honour it in this way has truly been a blast, and I can't wait for people to see it."

The pair then joked about rebooting 'Only Murders In the Building' in years to come.

Yelling with just half his mouth, Martin - who plays Oliver Putnam - exclaimed: "Let's solve the crime!"

Laughing, Selena - who portrays Mabel Mara - said: "Let's do it however long you can make it."

Martin said: "I don't think I'd be in every episode, what do you think? Just occasionally. What does Oliver think?"

He then slumped back in his chair and silence before he added: "That's it."

Selena said: "This is my life every day."

Earlier in the interview, Martin had asked his guest who was his favourite between her and their 78-year-old co-star Steve Martin, who plays Charles Hayden-Savage.

She quipped: "I don't believe there are favourite olds.

"I love both of you for exactly who you are and where you are and what you've taught me. It's just great."
