Emin, 37, was born in Baku, Azerbaijan, the son of Aras Agalarov, a billionaire developer, and moved to Russia when he was 4, according to his website. He went to high school in Switzerland and to college in the US at Marymount Manhattan College and joined his father's company, Crocus Group, becoming a commercial director in 2001.
In 2013, his song "In Another Life" was promoted in the Miss Universe pageant, owned at the time by then-"Apprentice" host Trump and held that year in Moscow. Emin's father paid between $14 million and $20 million to bring the pageant there, according to the Washington Post
, and Emin performed the song during the show and he released multiple music videos for the song, including one featuring contestants and another featuring Trump.
Trump tweeted about Emin following the pageant.
Emin has had one song chart in the US on a Billboard chart, "Boomerang" featuring Nile Rodgers, which peaked at No. 9 on the Dance Club Songs chart in 2015.
Emin congratulated Trump on winning the 2016 election on Instagram, sharing a video that also included footage of Trump wishing him a happy birthday.
One week after Trump reached the number of delegates to clinch the Republican presidential nomination in 2016, his son Donald Trump Jr. received an email from music publicist Rob Goldstone saying Emin
was offering "official documents and information that would incriminate Hillary."
Goldstone seemingly confirmed that meeting in a post on Facebook, checking into Trump Tower on June 9.
He also congratulated Trump on winning the election, posting the video of "In Another Life" and writing that Trump "will be the only American President ever to appear in a music video."
Goldstone wrote last month that he left the US for London as part of a "gap year," writing, "That's it NYC - see ya next year."
Emin posted on Instagram Tuesday a photo of him in a car, writing in English, "Finally sunshine," and in Russian what translates roughly to "look at this news right now."
Emin and Aras Agalarov have retained outside counsel to answer questions related to Trump. An attorney for Emin confirmed he and his father helped facilitate a meeting between Donald Trump Jr. and a Russian attorney, but denied the purpose of the meeting was to share incriminating information about Hillary Clinton, stating instead it was to discuss the Magnitsky Act, about Russian adoption. However, in the emails between Trump Jr. and Goldstone, the act is not discussed.
"If there was something important that Mr. Agalarov wanted to communicate to the Trump campaign, I suspect he could have called Mr. Trump directly as opposed to having his son's pop music publicist be the intermediary," Agalarov attorney Scott Balber told CNN's "New Day" Wednesday.
