Red lips never really go out of style, and lately, celebrities have been experimenting with the hue of their crimson pouts.

For months now, dark red lips have been one of the hottest fashion trends, with everyone from Rihanna to Bella Thorne rocking deep red lips. Dark lips suit all of the notable female celebs we've included above, but which of them do you think looks best with this shade of lip rouge?

The first row kicks off with Rihanna and Katy Perry, who do not shy away from bold colors. Their dark red lips give these pop divas that extra edge they always crave. The same can be said for Cher Lloyd, Rita Ora and Lady Gaga, who are all fashion risk-takers that have slicked on dark rep lips before hitting the town.

In the second row, you'll see 'Summertime Sadness' songstress Lana Del Rey looking very vamp-y with her crimson pout, as well as 'Shake It Up' sweetheart Bella Thorne, who looks beautiful with those dark red lips against her peaches and cream complexion. Carefree spirits Demi Lovato and Jessie J also nail the red lips, as does 'Spring Breakers' star and '$$$ex' singer Vanessa Hudgens.
