Fans are still quite curious as to who Austin Mahone's girlfriend actually is. The 'Mmm Yeah' singer, so far, has been linked to three singers.

The 18-year-old singer expressed his "fancy" to Little Mix member Leigh-Anne Pinnock in the past. He almost kissed rapper Becky G during an award show some time ago, as well.

However, the girl that Mahomies suspect is the closest to his heart is Fifth Harmony's Camila Cabello. The pair first sparked rumors with Mahone's cryptic tweets back in March. Later, the pair openly flirted on the social media site, which eventually turned into selfies on Instagram. They also went out on movie dates and even went were nobody should.

Despite denying any romantic connection between the two, supporters of the rumoured couple are rooting for them to end up together.

With Fifth Harmony joining the 'All I Want' singer on tour, they have more chances to hang out and get to know each other better.

Who knows? Maybe their close friendship could turn into something more romantic.
