Miley Cyrus Says She's 'Fine' But 'Worried' About Sister During Parents' Divorce

Hours after the news broke of her parents' divorce, Miley Cyrus was on the air in Chicago promoting her new single, "We Can't Stop," from an upcoming, still-untitled pop album. 

"She was in a really good mood, and she was talking about how she worked with Snoop Dogg on her album, and we asked her about her hair and her new look,"Showbiz Shelly, entertainment reporter for B96 Radio in Chicago, tells PEOPLE of the Friday broadcast. 

But after the interview, Cyrus – whose father, Billy Ray Cyrus, and mother, Tish Cyrus, announced their split to PEOPLE late Thursday – opened up about more personal matters, including concern for her little sister, Noah.

US radio star Rush Limbaugh's health scare over

Right-wing US talk show host Rush Limbaugh says tests taken after he was admitted to hospital with chest pains showed nothing wrong with his heart.

Mr Limbaugh said he was being released from the Queen's Medical Center, in Honolulu, Hawaii, where he had been since Wednesday.

He said he did not know what had caused the chest pains.

Mr Limbaugh, 58, is highly influential in the US and his radio show is one of the most popular in the country.

It is broadcast on some 600 stations across the country and heard by more than 14 million people every week.

Earlier, standing in on Mr Limbaugh's radio show, guest host Walter E Williams had described the radio star's pains as similar to the feeling of a "heart attack coming on".

But doctors said Mr Limbaugh had not had a heart attack and did not suffer from heart disease, the Associated Press news agency reported.

Mr Limbaugh is in Hawaii on holiday.
