With February sweeps about to begin, Ellen DeGeneres is reportedly upping the ante for her daytime talk show, enticing her television audience with appearances from some of the biggest stars -- from Christina Aguilera to First Lady Michelle Obama. One joint interview we're especially excited about is her upcoming chat with Taylor Swift and Zac Efron, who will be talking about their Dr. Seuss film 'The Lorax,' which hits theaters on March 2.

Last week, the young celebs had to fend off rumors of a love spark after they were spotted dining together and laughing at the Los Angeles Italian eatery Pace. A source put those whispers to rest, however, saying that the two were working on promotional efforts for 'The Lorax' and were doing “press stuff together and after they were done, they decided to grab dinner.”

Still, Ellen DeGeneres may bring this up in her interview just to get a direct response from the two. This season, she'll also be interviewing all four celebrity judges from 'The Voice' -- it'll be part of a pretty packed lineup.

Swift and Efron's 'The Ellen DeGeneres Show' appearance will air on Tuesday, Feb. 21.
