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.
When asked how she's doing in the
wake of the divorce news, Shelly says
Cyrus, 20, said, "Oh, I'm fine. I'm
okay."
Shelly says she also said her parents'
divorce after 19 years of marriage
won't be that noticeable for the singer
because of her busy travel schedule.
"I'm much more concerned for my
sister [Noah]. She's 13," Cyrus said,
according to Shelly, whose real name
is Michelle Menaker.
On Friday Noah Tweeted , "Please pray
for me and my family."
(Tish is requesting primary physical
and legal custody of Noah with
visitation for Billy Ray, according to
the documents filed Thursday in L.A.
Superior Court.)
But Miley was upbeat during her time
at B96 in Chicago, where she's
introducing Macklemore and Ryan
Lewis at the B96 Pepsi Summer Bash
this weekend.
"With everything that's happened, she
was very nice and really didn’t seem
affected. If she was, she was covering
it up really well," Shelly tells PEOPLE.
"We really enjoyed having her."
