Twitter is a remarkable technology — allowing us to keep up with the made-up thoughts of a hologram and reduce all art to pithy put-downs and puns. It also provides access to the pyches of some of the biggest starts on the planet—including Justin Bieber, who had a weird little run with his smartphone on Sunday.

In the midst of what he referred to as a “Random Twitter Hour,” Bieber wrote, “Dear mariah yeeter…we have never met…so from the heart i just wanted to say…” with a link to this odd audio clip from the Borat movie.

Yeater is, of course, the woman who accused Bieber of impregnating her somewhere in the bowels of L.A.’s Staples Center after a concert. The paternity suit was withdrawn after Bieber took a DNA test proving he was not the father of Yeater’s infant son.

The rest of his “Random Twitter Hour,” which goes out to some 21 million followers, was indeed random, featuring such nuggets as “Why does David Ortiz look like Robocop?” and simply, “My loins.”

Meanwhile, you can no longer re-tweet Nicki Minaj’s random thoughts, because the platinum rapper has shut down her account. “A voice in my head told me to delete my Twitter and that’s what I did,” she told British talk show host Graham Norton shortly after calling it quits. She also noted in other interviews that she was bothered by the fact that certain sites had leaked her music and that she was tired of the negative reactions to her work on Pink Friday: Roman Reloaded (she also threatened to retire from music completely, which seems like sort of a rash reaction to strangers not liking “Beautiful Sinner”).

Minaj left 11 million followers on the table, joining the ranks of other tweet-happy stars — including Chris Brown, John Mayer, Alec Baldwin, and Demi Lovato — who have walked away, though many of them end up coming back later (we’re looking at you, Miley Cyrus).

What do you think? Was Bieber’s tweet ill-advised? Will Minaj be back? Give us your #thoughts below.
