On Tuesday afternoon, Olivia Wilde [1] was spotted out and about in NYC with her growing baby bump in tow. The Vinyl star — who is currently pregnant with her second child [2] — kept things casual in a black tee and ruffled skirt as she ran a few errands around town. Noticeably missing were Olivia's fiancé, Jason Sudeikis, and their adorable son [3], Otis, though Olivia did take to Instagram over the weekend to share a cute photo of the pair [4] in honor of Father's Day [5]. Along with the snap, she wrote, "Happy Fathers Day to all the kind, supportive, fun, hilarious dads out there. Especially this one." Take a look at even more sweet moments between Olivia and Jason that are guaranteed to steal your heart [6].
