Rihanna in her 2007-2008 GGGB phase and in her 2010-2011 Loud phase
Shakira in her 2001-2006 phase Laundry Service and Oral Fixation years. more so on her Laundry Service years I mean have any of yall seen Underneath your clothes? dam she was smoking but much more naturaly beautiful in her Oral Fixation era
Britney from 1999 to 2003 ish she was the blond bombshell of the music world
J-Lo was smoking back in the day but she seems to have peaked in like 2010 in her comeback which is amazing at her age
Beyonce in her B'day era was stunnning!!!!
Lana Del Rey is in her peak now !
the others were always just average I guess.
I dont think Bey's beauty even has a peak. She had flawless looks in all her eras except DIL. She's been the most beautiful popstar to me since b4 i knew what it meant to stan for popstars so no bias here
Just kidding, she hasn't peaked yet 
Oh, and Mariah from 1997-2001
