But we bet you didn't know they ate cake -- a lot of cake -- while they were here. Here's where.
The on again, off again duo was spotted grubbing at River North hot spot HUB51 with a party of 8 that included Lindsay’s little sister Ali. They capped off their meal with HUB’s infamous “Martha’s Carrot Cake” in honor of Ronson’s recent 32nd birthday.
On Sunday night the sugar fest continued at Ronson’s Supra Sneaker Launch party at Angels and Kings where she spun from 12 to 2 am. Afterward, she was presented with a cake designed by Chicago's Angel Food Bakery and baker extraordinaire Chef Stephanie Samuels. The cake was created to be a replica of Ronson's recently launched Supra sneaker line.
Now you know.
