Ariana Grande on Twitter Thursday unveiled plans for her “Sweetener” world tour, which launches in March and ends with a show at Barclays Center on June 14 and Madison Square Garden on June 18.

Ticket sale information is still being finalized, though American Express cardholders can buy pre-sale tickets starting at 10 a.m. on Nov. 1.

The tour announcement came in the midst of news of her breakup with fiance Pete Davidson and the death of her ex-boyfriend, Mac Miller. Grande told fans on Twitter that she has coped with the stress by working on new music and has finished another album. “How u think I survived these 2/3 months” she tweeted to a comment about finishing an album.
