Gigi Hadid is 'complete happiness' for 'much-in-love' beau Joe Jonas

If you'll ask the mad-in-love Joe Jonas to describe happiness, he will simply tag it with his new girlfriend Gigi Hadid.

During a recent interview, when the 26-year-old singer was asked, "If I said the word Gigi, what comes to mind," he replied, "Happiness," with a giant smile, reports E! Online.

The duo took their friendship to another level earlier this summer and it seems like their relationship is sailing high.
