Anna Kendrick and Bill Hader shocked the public upon learning about their secret romance. Sources recently revealed that they have begun dating amid the pandemic, and are now in a relationship for over a year.

Speaking to Star, the insiders asserted that the two celebrities are "a good match," although they might look like an "odd pairing" for some. They have the "same quirky sense of humor," adding that they both are "a little high-strung."

Hader and Kendrick are reportedly living together, as well. As alleged, the latter has already moved into the former's home and even met his three daughters.

While the relationship is "pretty serious," it is claimed that neither of them is hurrying to tie the knot.

Following the shocking news, though, no one can confirm whether Anna Kendrick and Bill Hader are, indeed, dating. They have yet to make any official statement, with reports saying that their representatives "declined" to comment.

Accordingly, the latest assertions in Star for its February 14 issue remain uncertain. The insiders of the outlet did not provide any proof about the relationship, as well as the narrative of them living together under one roof.

The dating reports involving Bill Hader and Anna Kendrick first emerged in mid-January. People learned from sources that they have been secretly dating for more than a year.

The same insiders noted that the "Saturday Night Live" alum and "Pitch Perfect" star are "very private people." Moreover, it was easy to keep things under the wrap because of the COVID-19 pandemic.

Kendrick and Hader are, also, described as "both hysterical," hence, "they must keep each other laughing all of the time." In the end, the actress is stated to be "really, really happy" about her relationship with the comedian.

Amid the continued talks about the reported relationship, Cosmopolitan released a "potential" timeline of the two celebrities' romantic links. As stated, Anna Kendrick and Bill Hader likely first met on the set of "Noelle," which began filming and production in October 2017.

At the time, though, "nothing romantic happened" between the then-co-stars. Hader was still married to Maggie Carey, with whom he shares his three daughters, while Kendrick remained tight-lipped about her love life.

The "SNL" star and Rachel Bilson separated after dating for months, starting from late 2019 up to mid-2020. Sometime between July and December of the said year, the "Noelle" co-stars reportedly started to date each other in secret.
