Speaking to *PEOPLE*, Reinhart explained that her actual birthday on September 13 was spent resting, as she felt unwell following her travels through Brazil and Europe. Despite feeling ill on her special day, she made the best of the situation. “I had a beautiful cake. I sat in the pool. I was with my boyfriend and we watched *13 Going On 30*, as one does on their 30th,” she recounted, highlighting the comfort found in familiar joys during a significant life milestone.
*13 Going On 30* follows the whimsical tale of a young girl, Jenna Rink, portrayed by Jennifer Garner, who, after making a wish at her 13th birthday party, finds herself navigating life as a 30-year-old fashion editor the very next day. The heartwarming film remains a cherished classic, and Reinhart’s choice to rewatch it on her birthday illustrates her fondness for it, particularly as she has been giving nods to various rom-coms during her press tour for *The Love Hypothesis*.
During the promotional events for her film, Reinhart paid tribute to *13 Going On 30* not just in spirit but also through her fashion choices. At a press event in New York City on September 17, she donned a polka-dotted coat similar to that worn by Garner’s character, accompanied by a stylish lingerie dress that evoked nostalgia for the early 2000s. This ensemble was part of a series of outfits that referenced iconic moments from various rom-coms, including *How to Lose a Guy in 10 Days* and *Miss Congeniality*.
Looking ahead, when asked if she had additional plans to celebrate her birthday, Reinhart revealed modestly, “Not really.” However, she will extend her upcoming trip to Paris, adding a dash of adventure to her milestone year. “That’s my 30th,” she remarked, referring to the trip as a personal celebration.
Reinhart expressed her contentment regarding her birthday festivities, stating that the press tour for *The Love Hypothesis* itself felt like a celebration of her turning 30. “I would not have wanted to celebrate the last month any other way,” she added. The actress, known for her appreciation of iconic film fashion, also shared her thoughts on potentially including other rom-com-inspired looks during her promotional appearances. “No, this is it,” she insists. “I think we checked a lot of boxes and did it.”
*The Love Hypothesis*, which is now available for streaming on Prime Video, features Reinhart in the lead role, alongside actor Tom Bateman. The film is based on Ali Hazelwood’s bestselling novel and tells the story of Olive, a Ph.D. candidate who finds herself in a complicated scenario involving her best friend’s crush and a fake relationship with a daunting professor.
As Olive embarks on a journey of self-discovery and love, the film explores themes of friendship and the risks associated with romantic entanglements. According to the synopsis, Olive’s impulsive kiss with the intimidating Adam Carlsen leads to unforeseen circumstances that push her to confront her own feelings and desires.
In celebrating her 30th birthday through a mix of self-care, film nostalgia, and professional achievements, Reinhart seems ready to embrace this new chapter of her life with a blend of reflections on her past and excitement for what lies ahead.
