Austin Mahone Feels 'Blessed' After 'Amazing' Los Angeles Concert

Fifth Harmony is currently opening for Mahone on his headlining summer tour, which was in Las Vegas yesterday. Mahone was recently linked to singer Becky G after the two presented an award together at the 2014 Premios Juventud Awards in Miami last month.

Things got pretty steamy when Becky G looked at Mahone and got closer to his face, while the Mmm Yeah singer stared seductively at her. While Becky G is speaking in Spanish, Mahone says "and they kiss?" Before Becky G pulls away from him.

Afterwards on his Instagram, Mahone wrote "Always good to see @iambeckyg," with a photo of the two of them together. Becky G responded by writing on her Twitter account "@AustinMahone always good seeing you too:)"

Mahone and Fifth Harmony's next tour stop is August 2 in San Jose, Calif.
