Selena Gomez is going to ''spoil'' her baby sister.

The 'Come and Get It' hitmaker's mother Mandy Cornett gave birth to a daughter last Thursday (13.06.13), and the singer can't wait to bond with her stepsister and shower her with gifts.

In an interview prior to her sister's birth, she told aufeminin.com: ''I want to be the best sister in the world. I'm really going to spoil the baby! I can't wait.''

However, the 20-year-old star realises her new sibling will be much younger than her and thinks she may end up more like the tot's aunt than a sister.

She said: ''There's going to be a big age difference, so I think I'm going to be more like a cool aunt.''

The singer-and-actress also revealed that her taste in men has changed as she's gotten older, although she isn't looking for a new beau following her split from teen heartthrob Justin Bieber earlier this year.

She said: ''You grow up, you change and your tastes change too. It's always evolving. What do I look for in a guy? Someone I can have fun with. To be honest, I'm not really thinking about that at this moment in time, so we'll see!''
