Despite the numerous reports suggesting that Demi Lovato and Wilmer Valderrama have ended their relationship, RadarOnline quotes a source saying that all is well with the star couple.

In fact, rumors about the couple's break-up started floating about the Internet since the 34-year-old 'That 70's Show' star Valderrama's Twitter handle was hacked last July.

RadarOnline quotes a source claiming, "Demi and Wilmer are not broken up," adding, "They are still a couple and very much in love. They are both really busy working on their own things right now. Demi has been focusing on her music and releasing new material, and Wilmer is busy promoting his new TV series From Dusk Till Dawn."

Elaborating further, the insider told RadarOnline, "They have been through a lot together," and "The great part about their relationship is that they have a lot of trust."

RadarOnline says, "Trust is not something that has come easy to Lovato, who has been an outspoken voice in Los Angeles' sober community for over two years."

The source also confided, "Wilmer is not sober, so her friends sometimes worry that he could lead her back to dangerous old habits," and goes on to say, "But Wilmer is not an addict and respects her sobriety very much. Demi is like a rock and is very dedicated to remaining sober."

In fact, the "Really Don't Care" 21-year-old singer Lovato and Valderrama has had an on-again, off-again relationship since they began dating in 2010. Despite the fact that Lovato dedicated a sweet birthday message to her fiancé early in 2014, the couple usually keeps things about their relationship secret.

In 2013, Lovato released her fourth studio album, and will go aboard on her Demi World Tour in September. On the other hand, Valderrama currently stars as Carlos Madrigal on El Rey channel's 'From Dusk Till Dawn' series.
