Ariana Grande good to fans

Ariana Grande is celebrating her album by chatting to fans.

The American singer released Yours Truly at the end of last month and has since then been busy promoting her new music.

She's received great reviews, including being dubbed "the new Mariah Carey" and her first single from the album, The Way, peaked in the US Billboard top ten.

"Have a surprise for you guys tonight," she teased on Twitter.

"Wanna know what the surprise is? It's not the Baby I music video just yet! lol that's coming in a couple days though I promise

"Tonight in celebration of my album to thank you for everything, me & the crew are doing a massive live chat at 9pmEst/6pmPst! See you then (sic)."

Baby I is the second single from Yours Truly and it peaked at number 21 in the US Billboard charts.

Ariana has also teamed up with The Wanted's Nathan Sykes on track Almost Is Never Enough, which will appear on movie The Mortal Instruments: City of Bones.

"Can't wait to perform on @kellyandmichael this morning with @nathanthewanted! #almostisneverenough 1 of my favorite songs from Yours Truly!! (sic)," she gushed on Twitter.

Ariana and Nathan have become close and are rumoured to be dating, although the 20-year-old brunette claims they are still trying to "figure things out".

However, her alleged romance with Nathan, also 20, seems to have got her thinking about other cute couples.

"Blair is not Blair without Chuck (sic)," she cryptically tweeted, referencing Gossip Girl lovers Blair Waldorf and Chuck Bass, who were played by Leighton Meester and Ed Westwick.

Yours Truly is out now.
