Singer gushes over Selena Gomez's new sexy curves

Justin Bieber, 21, finds his ex girlfriend, Selena Gomez, 22, sexier than ever and has become a huge fan of her new curves.

The 'Boyfriend' singer reportedly told Selena she looks sexier than she's ever looked and he's been keeping tabs with her 'sexy photos' she's been posting online while on vacation in Mexico.

Well, now that Selena and Russian boyfriend, Zedd, 25, have broken up, is her former fling, Justin planning on winning her back?

''It’s not only him[Justin] that’s telling her how hot she looks,'' a source tells Hollywoodlife, ''Selena has been getting nothing but love from guys for her new curves, so that’s helped her confidence.''

Although the Biebs may have been flirting with Kendall Jenner and recently Ashley Moore, sources claim he still wants Selena to be his girlfriend.

Meanwhile, Selena is enjoying life after her breakup from Zedd, and is loving the attention she gets from other guys!
