Spectators could be forgiven for losing concentration on the tennis at the weekend, being captivated instead by Sweden's delightful little Princess Estelle.
The adorable one-year-old Princess, who was dressed in a cute pink, grey and white dress with a matching pink bow in her hair and pink booties, looked like she was having a great time at the Stockholm Open tennis tournament.
Estelle also wore another pink bow – along with both her parents – in support of National Breast Cancer Awareness Month.

Not so interested in the final match between Spain's David Ferrer and Bulgaria's Grigor Dimitrov, the young royal was entertained by the rows of tennis spectators, taking in all the movements and goings-on around her.
When she wasn't peering over the edge of the barrier, holding it tightly with her little fists, Estelle was resting her legs on the ledge and beaming from ear to ear.
Her doting parents, Princess Victoria and Prince Daniel, were equally as thrilled by the game and their young daughter's antics.
Dressed in a white blouse with her hair swept back into a bun, 36-year-old Victoria laughed happily by her husband’s side.
All the while, the royal, who is next in line to Sweden’s throne, kept a watchful glance over her little one.
Estelle will soon have another little Prince or Princess to play with. Her aunt Princess Madeleine is currently pregnant with her first child, which is expected at the start of March next year.
Palace officials confirmed in early September that the couple "are delighted to announce that the princess is expecting their first child".
In July, fresh from their romantic Seychelles honeymoon, the 31-year-old royal sidestepped questions about their plans to start a family, saying: "Right now we are enjoying our life as newlyweds."
