Jessie J lent her support to Channing Tatum during the opening night of his 'Magic Mike Live' show in London on Saturday (10.11.18)

Jessie wrote: "Congratulations @channingtatum what a show... Ladies and Gentlemen you don't want to miss this. (sic)"

The singer's appearance at the event in London came shortly after Channing and his five-year-old daughter Everly attended a performance by Jessie in Los Angeles earlier this month.

The 38-year-old actor and actress Jenna Dewan announced they'd decided to split in April this year, having been married since 2009.

At the time, the high-profile duo issued a statement that read: "We have lovingly chosen to separate as a couple. We fell deeply in love so many years ago and have had a magical journey together. Absolutely nothing has changed about how much we love one another, but love is a beautiful adventure that is taking us on different paths for now. There are no secrets nor salacious events at the root of our decision - just two best-friends seeing it's time to take some space and help each other live the most joyous, fulfilled lives as possible."

Since then, Channing has started dating the British pop star, and Jenna has been seeing the Tony Award-winning actor Steve Kazee.

A source recently said: "Jenna is having a lot of fun with Steve. They've been dating for months out of the spotlight and it's becoming more serious. They have a lot in common."

Despite this, Jenna and Channing are still supporting one another in their efforts to co-parent their daughter.

The insider added: "She and Channing are both very respectful of each other, but she's ready to move on with her life. She's feeling hopeful about the future and her friends are also really excited to see her so happy."
