Ariana Grande is having a summer of ups and downs. Her hits 'Problem' and 'Break Free' are ruling the charts, and she's counting down the days to the release of her new album 'My Everything.' On the other hand, she's dealing with the recent loss of her grandfather, and now a split from her boyfriend Jai Brooks.

A source told E! News that the couple ended once again last month, this time on Ariana's terms.

"When her grandfather was dying, everyone was there for her. People flew to Florida to be with her, but Jai didn't," the insider revealed. "Ariana just felt he wasn't there like he should have been."

The singer also tweeted a slightly cryptic message earlier today (Aug. 4), thanking her fans for their support and advising them to surround themselves with people who will be supportive through good and bad times.

Poor Ariana! She didn't let her reflective mood keep her down for long, though, returning to Instagram a few hours later to share a teaser of a new song from her album. 'Love Me Harder' -- could the title be another indirect? -- is a collab with the Weeknd, and from the sounds of the 15-second clip, it's another upbeat dance track.

Hopefully Ariana's busy promo schedule will keep her mind off of her losses! We're thinking of you, Ari!
