Jennifer Lopez started her 55th birthday with a relaxing bike ride in the Hamptons with her 16-year-old son, Max, on Wednesday.

Celebrating without her estranged husband, Ben Affleck, who missed her extravagant Bridgerton-themed party, Lopez enjoyed quality time with her son, whom she shares with ex Marc Anthony.

The duo biked to Pierre’s French restaurant, where a friend joined them, sporting a pink and silver ‘Happy Birthday’ headband.

Lopez looked stylish in a $3,400 white and aqua Dior mid-length shirtdress, paired with studded flats. She accessorized with a sleek ponytail, oversized sunglasses, a straw tote bag, and statement earrings.

Her massive green diamond engagement ring remained on her finger despite rumors of marital issues after spending her second wedding anniversary apart from Affleck.

Max was dressed in an all-white outfit with brown sandals. The mother-son pair dined outdoors before heading home on their bikes.

This celebration was much quieter than her lavish weekend party, which featured a horse-drawn carriage and period-era costumes inspired by Netflix’s Һit show Bridgerton. Guests arrived in elaborate garments for the celebration, where Affleck was notably absent.

Lopez shared a video from the bash, showcasing Regency-era dances and at least two wardrobe changes. She looked like the diamond of the season, singing into a microphone, blowing out her candles, and enjoying orchestral music.

Reports of Jennifer and Ben facing marital issues have surfaced, with speculation about a possible divorce. Despite this, JLo wished Affleck a Happy Father’s Day, and the couple attended Violet’s high school graduation together. Their $60.85 million Beverly Hills home is now on the market, further fueling rumors of a split.
