Single and smiling in the city!

A radiant Blake Lively put her best foot forward in NYC on Wednesday, the day after Us Weekly broke news of her split from Leonardo DiCaprio.

The Gossip Girl actress, 24, stopped by the Renaissance Hotel in Manhattan to check out their "Dare to Check In" Halloween room, a "scary" themed room that Renaissance guests can check into at locations nationwide during this season.

"She is super into Halloween. That's why she [came to the preview]," an observer told Us, adding that Lively was in a "fun" mood and even read tarot cards for one fellow attendee. "I was impressed!"

"She did not seem fazed by Leo at all," the witness adds.

Although the pair had been hot and heavy since kicking off their romance in Europe in May, the Oscar-nominated DiCaprio is "looking for someone to eventually start a family with," one pal told Us. "That's not where she's at. She's only 24!"

Added another source: "He's more mature. They're not in the same place right now."
