LOS ANGELES, Aug. 8 (UPI) -- Demi Lovato and Wilmer Valderrama are reportedly still together.
Breakup rumors have been flying about the 21-year-old singer and 34-year-old That 70's Show star since Valderrama's Twitter was hacked in July, but a source tells RadarOnline all is well with the couple.
"Demi and Wilmer are not broken up," the insider asserts. "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."
"They have been through a lot together," the person added. "The great part about their relationship is that they have a lot of trust."
Lovato and Valderrama have been an on-again, off-again couple since 2010. The pair keep their relationship tightly under wraps, although the singer did dedicate a sweet birthday message to her beau earlier this year.
"To the funniest, most inspiring, incredible man I know.. @WilmerValderrama," she captioned a post on Instagram. "Thank you for helping me get through my darkest moments. You are truly a light to this world and to my life. Happy Birthday!!!"
Lovato released her fourth studio album, Demi, in 2013, and will embark on her Demi World Tour in September. Valderrama currently stars as Carlos Madrigal on El Rey channel's From Dusk Till Dawn series.
