Of course being a pop star now-a-days you videos are essential to the single. A part of what makes a good video is how believable the artist looks in the video. Which pop star is the best actress in her music videos?

They all have their good moments and of course they're not-so-good moments. Based off most recent videos I'd vote Rihanna, though.

TBH, Gaga's videos are the only ones that require acting.

Britney Spears. The way she puts on perfume, Angelina Jolie could never.

the WFL video was so good because it was so believable thanks in large part to Rihanna...

Criminal, WFL, Man Down??

Not necessarily for any video that anyone releases the music artist has to have some acting ability to make the video believable and not look like some low budget middle school talent show

I agree although WFL isn't my favorite Rihanna song the video brought it to that level. Largely due to Rihanna's believe-ability

yes ... and even the one that got away

and RUSSIAN ROULETTE and kinda te amo :P

This year, a lot of girls made videos with story lines and displayed some good acting

Did Rihanna really have to act to play a drug-addicted fun-loving sex-maniac though?

I thought TOTGA's acting was horrendous I laughed at the part that was suppose to make the viewer cry

she didn't just play a part, she brought a character to life. Every1 that i've talked to that's watched the video has said that they were shocked by how believable it all seemed....

If I Were A Boy was very convincing.

Britney's acting is laughable. Gaga's is actually quite convincing.

I guess ultimately it depends on the singer, song, and director of the video.

One that comes to mind is Britney Spears in the "Everytime" video. The scene where she starts to sink into the tub always gets me.

Funny because Britney's has been hailed by critics.

I think Katy is pretty good at playing the fun/comical characters...
