Los Angeles, Mar 8 (IANS): American actor Justin Hartley says he is a little upset with the writers of TV series "This Is Us" for not giving him a nude scene yet.

Hartley spoke about the show on talk show "The Talk" on Monday, reports people.com.

Asked if a nude scene has been presented to him yet, Hartley said: "You know, the thing about it is - no, I'm a little upset about it."

Hartley, 40, joked, "I mean, what does that say? Am I losing it?"

"This Is Us", which also features Mandy Moore, Milo Ventimiglia, Sterling K Brow and Chrissy Metz, revolves around the lives of a group of people with the same birthday, including Jack (Ventimiglia), whose wife, Rebecca (Moore), is expecting triplets in Pittsburgh.

The triplets are; Kevin (Hartley), a handsome television actor growing bored of his fly bachelor lifestyle, Kate (Metz), his funny and sweet heavyset twin, and Randall (K Brow), a big shot commodities trader in search of his biological father.

Hartley, who is father to adolescent daughter Isabella Justice off screen, is fine leaving nudity to his co-star Ventimiglia. Ventimiglia bore his bare buns for audiences to see in one of the episodes of the show, which airs in India on Star World Premiere HD.

Hartley said: "I just leave that (nudity) to him. He's very good at that."
