At 0:56 you can see Adam Levine tracking vocals with a ELA M 251 Microphone.

A "favorite" 251 was used for vocals on Love Is a Four Letter Word, as stated by producer Joe Chiccarelli in this July 26, 2012 Universal Audio blog interview.

It was his favorite Telefunken 251 through a Sunset Sound mic preamp into a Universal Audio 1176 Limiter. He’s used 1176s for many, many years. He has them at home and in his studio. So we set up what he normally has at home at Sunset Sound for him to work on.

In the Netflix documentary "BLACKPINK: Light Up The Sky," Rosé can be seen using the Telefunken ELA M 251 microphone while harmonizing and singing.

Mentioned by A Head Full of Dreams co-producer Rik Simpson in this Sound on Sound article.

“My drum-mic setup mostly consisted of the usual contenders, apart from an old STC/Coles 4012 ‘ball and biscuit’ microphone as a mono overhead that I love, and a couple of Telefunken 251s as overheads. But everything else is fairly standard. I play around with different room microphones depending on a) how many band members I am recording at the same time and b) what the song needs. I quite like Coles, which are kind of grimy and dirty, and I quite like B&K microphones which are the opposite end of the sonic spectrum, a lot more hi–fi. I have a Shure 57 on the snare, but I sometimes go for a Neumann KM84 if the song is delicate and the snare needs that tender touch. For the kick I have a Telefunken M82 dynamic microphone that is designed for a kick drum and that sounds really good. It is punchy and big but not too clanky. The AKG kick-drum mics are a little bit ‘knocky’ for my liking.

He talks about how he uses the (Telefunken) 251 at 9:46

One of Beyoncé's primary microphones. She can be seen using a Telefunken Ela M 251 for the recording of "Partition" in this video at 0:57.

The Ela M 251 was also used to record Beyoncé's vocals on Coldplay's "Hymn for the Weekend", as mentioned by A Head Full of Dreams co-producer Rik Simpson in this Sound on Sound article.

Beyoncé’s vocals were done at Chris’ house on the East Coast. It happened very quickly and was very home–grown. We built a vocal booth for her in the bedroom of Chris’ kids. I just came in with a laptop and an Avalon mic pre, and she favours a Telefunken 251. It was great because she is an amazing singer. There was really no comping done. We put the bridge part in loop and she sang over that, and once she had to figured out what to do she layered her parts. I literally used all of it. I did not have to do much to it, it is how she sounds.

According to this September 24, 2016 AudioTechnology interview with producer Stuart White, the 251 was also used on Lemonade.

“For the rest I have a Telefunken Ela M251 microphone, an Avalon mic pre, and a TubeTech compressor, all of which I used to record the majority of Bey’s vocals."

In this September 2018 Sound on Sound interview, White stated that 251 was also used on EVERYTHING IS LOVE.

He recorded both Beyoncé and Jay-Z with his “Telefunken mic, Avalon mic pre, and Tube Tech compressor. That was the chain for the entire album on both of them. I use just the one chain, because they jump back and forth on the mic all day long, and they both sound really good on that mic, so I kept it simple.”
