Photos : Beautiful Singer Selena Gomez Is Seen All Smile and Happy From Paris Fashion Show

The gorgeous songstress was spotted smiling and being so happy as she came flown back to the US from Paris Fashio Week, without boyfriend Justin Bieber, that si to say she can relax and breathe during an international long flight .

After a whirlwind vacation with Justin Bieber in the Caribbean and then a few days in the City of Lights for Paris Fashion Week, Gomez reluctantly returned to the U.S., on Wednesday, while bad boy Bieber stayed behind ... to cause trouble, no doubt.

The Biebs already lunched with Kendall Jenner -- without Selena -- the other day in Paris. Last night he was out on the town with Paris Hilton. What's next? Dinner with Miranda Kerr? who knows!
