TV column for Sunday, May 20

Billboard Music Awards, 8 p.m., NBC.

Expect lots of
female power tonight. Ariana Grande opens, Kelly Clarkson hosts and
Janet Jackson receives the Icon Award. Clarkson and Jackson sing –
the latter her first TV performance in nine years.

There will be lots
of duets -- Christina Aguilera and Demi Lovato, Macklemore and Kesha,
Salt-N-Pepa and En Vogue, Shawn Mendes and Khalid. Zedd and Maren
Morris will do “The Middle,” joined by Grey. Also: Ed Sheeran (in
Dublin), Camila Cabello, Dua Lipa and John Legend.

II: “American Idol,” 8-10:01 p.m., ABC.

It's music-overload
time. While many stars gather for the Billboard Awards, ABC seeks a
new star.

That's down to the
final three people. Tonight, Maddie Poppe, Gabby Barrett and Caleb
Lee Hutchinson perform and viewers vote. On Monday, we'll have the
16th “idol.”

ALTERNATIVE: “Masterpiece: Little Women” conclusion, 8-10:05 p.m.,

The first hour
focused on all four March sisters, each different and each
fascinating. But now it focuses on the one great character. On film –
from Katharine Hepburn in 1933 to Maya Hawke now – Jo has been a
wonderful tangle of steel and warmth.

There are also rich
little portraits of the others – the less-complicated Amy, their
wise and patient mother, the good-spirited guy next door. But most of
all, Jo lives forever.

Other choices

“Bob's Burgers”
season-finale, 7:30 and 9:30 p.m., Fox. By the second episode, Bob is
thinking of leaving the restaurant business. Then a couple wants to
have its wedding at the burger place.

“NCIS: Los
Angeles,” 8 and 9 p.m., CBS. In the first hour, a shoot-out brings
a tragedy (Sam is shot) and a break – information about the man who
kidnapped Mosley's son five years ago. That leads to the ninth-season
finale, with a daring mission to find the son in Mexico.

“The Simpsons”
season-finale, 8 p.m., Fox. After being hit by lightning, Bart feels
he sees ghosts.

Nine-Nine” season-finale, 8:30 p.m., Fox. For Fox, this might seem
like a logical end: Canceled after three seasons, “Nine-Nine” has
the wedding of Jake (Andy Samberg) and Amy. But the show isn't going
far; it's been picked up by NBC (Samberg's old turf), which will
bring it back at mid-season. Also tonight, Gina Rodriguez (“Jane
the Virgin”) plays Rosa's potential love interest.

“Madam Secretary,”
10 p.m., CBS. The fourth season ends with an extreme: A missile is
reportedly headed toward the U.S. and the president is planning a
retaliatory strike.

10:01 p.m., ABC. The team tries to stop a spy from stealing
top-secret information.

Masters,” 10:05 p.m., PBS. Fresh from “Little Women,” PBS
reruns this portrait of the woman who created it ... and lived it.
Like Jo, Louisa May Alcott grew up in a world of sisters, thoughts
and words. An abolitionist and a feminist, she wrote large adventures
for young people, then re-created the deep joys and tragedies of her
