Janet Jackson is hot for any age, not just 45. The successful R&B singer, sister of the late Michael Jackson, appears looking sexier than ever in a photo series on the Blackglama site, proving that she's still got the swagger she exemplified in her younger days.

Posing for Blackglama's 'What Becomes a Legend Most?' campaign, the 'Again' hitmaker rocks a series of flawless styles, even baring a bit of sexy skin in the name of the brand. In some shots, she's sassy, in others, sweet and seductive.

This is the second time Jackson has appeared as the face of the campaign, making her the first person in Blackgama's history to appear twice. CEO Joe Morelli explained Blackglama's decision to have the singer represent the campaign for a second time, saying, "It became clear in our discussions of who the Legend should be this year, that continuing the momentum with Janet made complete sense ... She embodies glamour, luxury, and sophistication, everything that Blackglama stands for."

We have to agree -- girl's got class!
