Before celebrating Valentine's Day with husband Ryan Reynolds on Tuesday, Blake Lively celebrated Galentine's Day in New York City with sister Robyn and mom Elaine.
It was all hearts and balloons when the gals showed up to an event on Monday night. Blake looked super festive in a SemSem blue mini-dress with red and white hearts all over it, and paired the style with a red sequin Chanel bag and black studded heels.
To top it all off, the 29-year-old actress had her hair done up in the shape of a heart.
Blake's older sister Robyn, 45, also got into the Galentine's Day spirit, stepping out in a red jumpsuit and red and white heart-shaped heels.
"Tonight's the night. Grab your best gal," Blake gushed on Instagram. "I love my man, but on this Valentine's, I celebrate women. Time to party."

The Gossip Girl star also shared a video of herself and Robyn getting ready for the party. "Thank you for the best nine to five out there," she wrote. "And thank you to all the hardworking people who made this party happen! Planning this event with you -- FOR WOMEN -- has been such a ball."
Last month, ET caught up with Robyn, who praised Blake for being a great mother to daughters James, 2, and 3-month-old Ines. "This is where she belongs," the former Teen Witch star, who has three children of her own, said. "She has my children and I have her children, [and] we're like, 'No, those are my children!' She's like, 'No, your children are my children.' We always argue about it. She's the best."
Robyn also had some advice for Blake when it comes to raising two kids. Check it out:
