Justin Bieber is doing everything he can do make Selena Gomez ''feel like his princess.''

The 18-year-old 'Boyfriend' singer - who recently rekindled his on-again/off-again relationship with the actress - isn't worried about going on a huge world tour next year because they are already planning to do everything they can to stay together.

A source told HollywoodLife.com: ''Selena will be making the trips she can when she isn't working, but June won't be a problem as he will be in the West Coast (of America).''

The couple - who briefly split last month amid reports the 20-year-old beauty felt she couldn't trust him - are now said to have their romance back on track and Justin has being doing everything he can to make her feel extra special such as lavishing attention on her at the recent Jingle Ball in Philadelphia, Pennsylvania over the weekend.

The insider said: ''Justin is crazy about Selena. It's just so obvious with the way he looks at her. Justin had a lot of people wanting to take pictures with him and talk to him at the Jingle Ball 'meet and greet' after the show and he just made sure to include Selena in everything -- he kept looking at her, smiling at her, they were side by side most of the time. It's like he really made an effort to make her feel like his princess.''

The couple were spotted at Marble Lane restaurant in the New York City recently where fellow diners said they looked ''happy and in love'' and only had eyes for each other.

Selena's close friend Taylor Swift is reportedly responsible for the reunion after encouraging Selena to forget about her ''trust issues'' with Justin.
