Serena Williams has added a second tournament to her comeback schedule.
The 44-year-old will make her return to professional tennis next week in London, where she will play doubles with Canadian teenager Victoria Mboko in the HSBC Championships at Queen's Club.
It was announced on Friday that Williams will also play doubles at the Berlin Tennis Open beginning on June 15, with a partner yet to be confirmed.
"Every tournament I add to my schedule right now feels special, and Berlin is no exception," the 23-time Grand Slam singles champion said on berlintennisopen.com.
"I'm excited to compete in front of the German fans and continue building momentum throughout the grass-court season."

The American has not played a match since a glittering farewell at the US Open in 2022, with Williams saying at the time she was "evolving away" from tennis.
Speculation has been growing about Williams' comeback since she reentered the anti-doping program -- a prerequisite for playing on tour -- last year.
And former world number one Lindsay Davenport revealed Williams' return might have come earlier had she not had to complete six months in the program first.
"I'd heard last year at the US Open she wanted to play mixed [doubles]," Davenport said. "She wasn't able to because of the drug-testing protocol."
Williams appears to have timed her comeback with Wimbledon in mind, and the first batch of wild cards for singles and doubles will be announced during the Berlin tournament.
Whether the veteran is eyeing singles at SW19 remains a source of great intrigue, but Davenport would be surprised if that is not her ultimate goal.
The former world number one said of Williams' return: "I think it's great. So many stories sometimes in our sport go negative. And I love that there's an excitement about a player returning.
