According to an onlooker, Suri and her mum Katie were spotted having an alfresco lunch in Central Park, New York City where the pair live. Katie's ex-husband Tom, who was absent from the celebration, is based in London.
"Suri enjoyed a low-key pre-birthday lunch Sunday with Katie, her maternal grandparents and two young girlfriends at Tavern on the Green," a source told People.

The group feasted on hamburgers, which cost an average of £15 at the grill restaurant, followed by the American eatery's famous cookies.
The source added: "Rather than cake and a rousing rendition of 'Happy Birthday,' Suri and her pals quietly opted for freshly-baked cookies from Tavern on the Go before heading off into sunny Central Park."
"Happy Birthday to my sweet angel Suri," wrote Katie
On Suri's actual birthday, the stylish youngster and her actress mum were spotted walking hand-in-hand in the streets of the Big Apple. Suri looked like she was ready for a party, dressed in a fuchsia summer dress and matching big bow in her hair.
Her proud mum took to Instagram to acknowledge her daughter's birthday, as she wrote: "So grateful for my favourite day of the year!!!!!! Happy Birthday to my sweet angel Suri."
Later that evening Katie, 37, attended the Tribeca Film festival where she showed off her sartorial prowess in Chanel printed high-waisted trousers and a black V-neck top.

Katie and her ex-husband Tom were married for six years until 2012. They welcomed their daughter Suri in April 2006, five months after tying the knot in a Scientologist ceremony in Italy.
Despite living in the spotlight, the former Dawson's Creek star has made a big effort to keep her little girl's upbringing as normal as possible, and to create unforgettable childhood memories like the ones Katie herself had growing up in Ohio.
Speaking previously about motherhood, Katie told Elle UK: "The number one thing is making sure my child feels loved. And good about herself. And that what she does and who she is, is special and important, and should be celebrated. And, as my mum always said, 'No one loves you like your mother.'"
