It's a sad day for Austin Mahone fans. The 18-year-old singer is wrapping up his United States summer tour tonight.

Why Austin Mahone Wanted To Sound Like Backstreet Boys & *NSYNC

Mahone has been on tour since late July with Fifth Harmony, Shawn Mendes and The Vamps all over the country. Mahone tweeted Wednesday, "LAST SHOW OF THE TOUR!!" On Monday, he had tweeted, "Family isn't just blood relatives, it's anyone who loves you unconditionally."

"It's going great and I'm having a lot of fun," Mahone told Just Jared Jr. in early August about his tour. "We have a ping pong table and a basketball hoop, so we're always playing around and having a good time."

Austin Mahone Reveals Whether He's Ever Been In Love

Mahone has toured before, but this was his first solo arena tour. He had previously played smaller venues this past winter and opened for Taylor Swift on her Red tour.

"We get into a group prayer and we all say a few words," he said about his pre-show rituals. "And then we go out there and kill it. I drink a lot of water to stay hydrated and stuff. Nothing too crazy."

The tour's last stop is Sterling Heights, MI on Wednesday. Afterwards, Mahone will head to Mexico City for a string of shows.

Mahone's plans after that? Working on his first full-length album. "I have one EP out now and the reaction has been great," Mahone told Cleveland.com last week. "After the tour I'm going back to Miami to work on my first full length. I'm excited to start recording."
