Gavin Rossdale posts pic with Sophia Thomalla after dating rumors

July 31 (UPI) -- Gavin Rossdale appeared to confirm Sophia Thomalla dating rumors over the weekend.

The 51-year-old British singer shared a first photo with the 27-year-old German model Sunday on Twitter following his divorce from Gwen Stefani.

"Having fun in Reno," he captioned a picture of himself and Thomalla posing in front of a private jet.

Rossdale performed with his band Bush at Silver Legacy Resort and Casino in Reno, Nev., on Saturday. He was first linked to Thomalla in March after he was spotted kissing the model during an outing in London.

"They're friends, introduced by a mutual friend," a source told People at the time.

Us Weekly reported in May that Rossdale and Thomalla are dating. The couple were spotted at an Italian restaurant in Indianapolis, Ind., on May 11.

"They shared a romantic meal," an insider told the magazine.

Rossdale split from Stefani in August 2015 after nearly 13 years of marriage. The singer, who shares sons Kingston, Zuma and Apollo with Stefani, opened up about their highly-publicized split in the March 3 issue of People.

"I just think that life is really complex, and it just works its way," he said. "It's just the way that it goes sometimes, and it's sad. I think that 20 years and three amazing children is quite incredible in and of itself."

"Raising three boys is [my] No. 1 [priority], then music comes right after them," the star added. "[Gwen and I] both just want the kids to be as safe and happy as possible, so that's the only focus we have."

Stefani herself has moved on with country star Blake Shelton. Shelton took the singer and her sons on a private helicopter ride this month following a visit to the Chicksaw Cultural Center in Sulphur, Okla.
