Ariana Grande, Rumored Boyfriend Nathan Sykes Perform 'Almost Is Never Enough' on 'Kelly & Michael': 'Yours Truly' Singer Releases Music Video Teaser for 'Baby I' [VIDEOS]

It's been only two days since Ariana Grande's stellar debut album "Yours Truly" hit store shelves and iTunes, but that doesn't mean the "Sam & Cat" star is slowing down. Grande performed her duet with The Wanted singer (and possible boyfriend) Nathan Sykes, "Almost Is Never Enough," on "Kelly & Michael" and released a music video teaser for "Baby I," putting promotion for her fast-selling album into high gear.

Today began with a sweet performance of "The Mortal Instruments" track and duet "Almost Is Never Enough." Wearing a crop top and high waisted, short flared skirt, Grande quietly sang the first verse and chorus before Sykes joined her onstage. The possible couple kept a fair amount of distance while belting out the words to the slow jam, but their chemistry was undeniable -- even hosts Kelly and Michael commented on their complimentary performance.

Of course, that's not all Arianators have to enjoy today. Grande unveiled a 30-second snippet of her upcoming music video for "Baby I." The short clip comes from near the song's end and shows a fun environment. Grande sports a white crop top and high-waisted shorts while dancing on the streets (Mariah Carey in "Heartbreaker" reference?) and does some small choreography amongst backup dancers and rafters in a city setting.

It seems as though the "Baby I" video will have a light, fun-filled vibe, with Grande expressing her youth and happiness while singing the banger.
