Former Disney starlet Selena Gomez is finding little to sing about, cancelling two concerts after her mother's miscarriage.

Gomez had to pull the plug on her Chicago and Seattle gigs to grieve in private with her family.

The entire Seattle concert is being postponed also by the medical problems of Gomez's fellow performer; doctors have ordered OneRepublic's frontman Ryan Tedder to rest his vocals.

In an exclusive statement to E! Online, Gomez's camp assures fans that the 19-year-old singer is doing well. But the representative confirms that a "family emergency" is behind the decision to back out of two live shows.

According to another insider, there was tragic news behind the cancellations - Gomez's mother, Mandy Dawn Cornett, has suffered a miscarriage.

Reports say Gomez was watching Power 106's Cali Christmas 2011 concert in Los Angeles when the devastating news reached her. She left for home immediately.

The young star has not released a personal statement since the news broke.

It is an unfortunate turn of events for the bubbly only child, who tweeted excitedly about her mother's pregnancy just weeks ago.

"Momma and Brian are finally letting me share the news... My mommys [sic] carrying my baby brother or sister," Gomez wrote on her official Twitter account.

"I'm the happiest girl in the world," she finished, obviously over the moon about finally having a little sibling.

It would have been Cornett's first child with Gomez's stepfather Brian Teefey. The couple has been married since the "Wizards of Waverly Place" star was five years old.

This personal tragedy is a dark cloud in Gomez's otherwise successful year. The singer-actress has shot to stardom in 2011, with her third album "When the Sun Goes Down" and the release of her big-screen venture "Monte Carlo".

She reveals to Hollywood Life that she's planning to focus on acting in the coming year.

"Next year I'll be starting to do doing more acting. I'll do two films in the beginning and then I'll probably go back to music," Gomez shares, quick to assure that she's not giving up on her music career.

"I'll balance them," she adds.
