Lady Gaga is obviously the biggest thing that happened to Pop since Britney.

In such a short amount of time, she achieved huge commercial success (an extimated 100M Gaga's records have been sold in little more than three years) and widespread critical acclaim, winning five Grammy Awards and being nominated for "Album Of The Year" three years in a row with all her three studio albums, while collaborating with a big number of music legends (Tony Benett, Cher, Elton John, Beyoncé, Brian May, Sting...), she swept award shows (http://atrl.net/forums/showthread.php?t=156262) and became a staple and an Icon in Pop culture. During this time, she was able to ammass an incredibly big and supportive (though often bitchy and psychotic) fan-base.

Her critical and commercial success remained strong during her Born This Way era, but, even if the album is the second best-seller of the year both in the US and WW and her Marry The Night video can still get an impressive 12M views in 5 days, the general feeling is that Gaga's popularity is slowly but steadily declining, as some factors (decreasing video views, declining singles success, apparent loss of interest within the general public) seem to show, and her Pop dominance seems to be threated by other girls, like Rihanna and Katy.

Her antics and her supposed "tryin' hard", along with her less commercial sound and darker videos, have turned off a considerable part of the public; for many, she's just a freak, a Devil worshipper, an Illuminati doll, a bitch who tries too hard, a copycat...; on the other hand, more people have started to realize her musical talent, her sincere and dedicated hard work, her genuinely kind behaviour towards her fans, and she has also succesfully started her activist role, defending LGBT and outcasts' rights (just yesterday, she had a meeting at the White House on these matters), she opened the Born This Way Foundation and she recently received the Trevor Project Hero Award.

So, what do you think? Is Lady Gaga still the biggest popstar in the world? If not, who stole her crown?

Messy

Not really.

Probably. I feel like her and Rihanna are kinda sharing it now.

She's one of the biggest

I think so, yes.

Yes, she is.

The girls can have more #1s than her, and? Her most successful era was The Fame Monster one, with zero #1s, so I think that argument is invalid. In album sales (Adele's not a pop girl), cultural impact + relevance, she's still the queen.

No. She lost her magic with Born This Way album

Yes

Even at her lowest, she's still pretty high. But I'd say her and Rihanna are the biggest.

Yes.

Yes...

.

Since Adele can't really be considered a Pop star, I'd say its Rihanna.

Lady GaGa is losing her charisma fast. I'm not saying she's flopping, but people are becoming less interested in her. Tbh, the only supporters she has left is her "little monsters", and her stanbase is huge. She is losing her likeability.

Yes. Even though she's not going through a hugely successful era, she is still dominating the headlines, her videos are still the most anticipated, she is still the biggest ratings draw and she is still the one everyone talks about. The other girls can't say the same. Rihanna and Katy are on a high right now, but they don't dominate culturally like Gaga does. They haven't made the same lasting impact that she has.
