People are celebrating Alfie Allen’s glow-up after he received an Emmy nomination on Tuesday for his role on the final season of “Game of Thrones.”

But Allen, who’s nominated for outstanding supporting actor in a drama series along with “Thrones” costars Nikolaj Coster-Waldeau and Peter Dinklage, was once the subject of a derisive song by his sister, singer Lily Allen – and fans are just now rediscovering it in the light of Allen’s nomination.

However, people were also quick to celebrate Alfie's nomination, despite the fact that his sister once called him "lazy" in her 2006 song, fittingly titled "Alfie."

And some even thought that Lily's put-down of her brother could've helped Alfie get more into character for "Game of Thrones."

In "Alfie," Lily Allen sings of her disappointment with her younger brother, who does nothing more than smoke weed in his room all day.

"Oh, Alfie get up it's a brand new day, I just can't sit back and watch you waste your life away," Lily says in the song.

"You need to get a job because the bills need to get paid," she says in the next verse, adding,"get off your lazy arse, Alfie, please use your brain."

In an interview shortly after she released "Alfie," Lily told Pitchfork why she wrote the song.

"When I wrote 'Alfie,' nobody really knew who I was," the singer said.

"At first [Alfie] was really upset about it, because he thought that I was just pointing out all of his bad points and attacking him. I thought it was really flattering."

In light of Alfie's recent Emmy nomination, however, Lily has been nothing but supportive, sharing a congratulatory message on her Instagram story.

"My baby f------ brother is nominated for an Emmy," Lily wrote in her story, saying "no one deserves it more."

A subsequent video posted to her story showed Lily crying "tear[s] of joy" for her little brother's nomination.

"I am so f------ proud of him, even without an Emmy nom," she said.

"But OMG, he has an Emmy nom. Go Alf!"
