Demi Lovato has officially split from Guilherme ''Bomba'' Vasconcelos. E! News confirms that the singer and MMA fighter broke things off a few weeks ago. An insider added that there's no "bad blood" between them, but that the pair realized they weren't working as a couple. Another source added, "Demi loves being in a relationship, but she is ready to be single for a little while." The pop star has deleted all photos of Vasconcelos from her social media. The former duo sparked romance rumors last year and made things official in January. In June 2016, Lovato split from her boyfriend of six years, Wilmer Valderrama.
