Justin Bieber took to Twitter to fight back reports that he fathered a child.

Justin Bieber has a message for those who believe the claims that he fathered a child: ” SANTA CLAUS IS COMIN TO TOWN B*Tches!”

Though Bieber’s publicist confirmed late Monday that the 17-year-old pop star will take a DNA test in connection with 20-year-old Mariah Yeater’s paternity suit against him, Bieber’s still using Twitter to fight Yeater’s allegations that they had sex and he fathered her young son.

“so this past week and even today every rumor and lie about me possible has been coming out in the press,” he tweeted today. “Just need to ignore it..but…even through all the crap and lies…my fans have been there for me.”

Bieber went on to say that his new Christmas album, “Under the Mistletoe,” reached the No. 1 spot on the Billboard 200 chart.

“WE ARE THE #1 ALBUM!!,” he wrote. “so to the people making up this BS……SANTA CLAUS IS COMIN TO TOWN B*Tches! #ILOVEMYFANS!!”

Bieber added, “they can’t break us!” and re-tweeted fans who avowed they’d stand by him.

Bieber has previously said that he writes all his tweets. His publicist did not immediately respond to ABCNews.com’s request to confirm that Bieber typed out his latest messages.
