She was the focus of attention last month when she sang Amazing Grace at the inauguration ceremony of the new Centre Court roof.
But Katherine Jenkins let the tennis take centre stage on Tuesday, as she checked out the action at the All England Club.
In what may have been a belated birthday outing for the Welsh opera singer, who turned 29 on Monday, she donned an elegant crisp-white sundress and metallic waist belt as she joined her mother in the royal box.
After watching the women's quarter-final round between Serena Williams and Belarusian Victoria Azarenka, tennis-fan Katherine enthused about her day on Twitter.
"We've just been given a glass of champagne. How civilised." She posted. "Just been watching Serena Williams - awesome! Having afternoon tea now. Wow, it's a scorcher."
