Anna Kendrick Tries to Steal Emily Blunt from John Krasinski on 'Lip Sync Battle'

Spike TV

Watch out John Krasinski! Looks like Anna Kendrick also has eyes for the beautiful Emily Blunt.

We already know Anna can sing thanks to her roles in Pitch Perfect and Into the Woods, but the 29-year-old actress outdoes herself in Spike's latest episode of their hit show Lip Sync Battle, going all out with her spirited performance of One Direction's "Steal My Girl."

She even came prepared with props -- in this case an adorable t-shirt with a heart-shaped photo of her with John's wife, which she just had to rub in his face.

Anna also brought in the big guns in response to John's rendition of "Proud Mary." J. Lo herself came out to lip sync her own single, "Booty," featuring Iggy Azalea!

So far, Lip Sync Battle has been the gift that keeps on giving. The star-studded show has already blessed us with Anne Hathaway's epic performance of Miley Cyrus' "Wrecking Ball" and her The Devil Wears Prada co-star Emily's sassy rendition of Blackstreet's "No Diggity."

Lip Sync Battle
airs Thursday nights at 10 p.m. ET on Spike.
