Selena Gomez "Sad" About Justin Bieber Break-Up, Says Source

Selena Gomez may have been all smiles at the Glamour Woman of the Year event earlier this week, but that doesn’t mean she’s happy about her split from her longtime boyfriend Justin Bieber.

A source revealed to E! Online, “She’s sad. It’s hard for her.” The Disney star has been trying to mend her broken heart by focusing on her business ventures. Besides recently launching her new Kmart collection, she will be heading to her hometown of Texas along with Ryan Seacrest to visit patients at the Children's Medical Center in Dallas.

After that, Selenita plans on hitting the studio for her upcoming fourth album. The source close to the star confirmed, "She's going to be in the studio. That's what she's focused on."

We are sure her muse tank is full after the split.
