Lana Del Rey is working with Mark Ronson.

The 'Summertime Sadness' singer has headed into the studio with the 'Uptown Funk' hitmaker to work on music for her upcoming third LP, tentatively titled 'Honeymoon'.

Speaking to Interview Magazine, Mark said: ''I'm going to do some recording with Lana Del Rey today and tomorrow. I found this cool old studio out here [in Los Angeles].

''She has some songs and I said I had some demo ideas, and if they are any good, then maybe she'll like them and we'll go from there.''

The record follows 2014's 'Ultraviolence' - which topped album charts in the UK and US - which the 29-year-old singer previously said is ''very different'' from the music she is working on for her next release.

Despite it being less than a year since she released her last collection, in January Lana revealed she already had nine songs ready for the album.

She said: ''I'm looking for a few more songs to tie everything together.

''It's very different from the last one and similar to the first two, 'Born to Die' and 'Paradise'. I finished my last one in March and released it in June and I had a follow-up idea. It's growing into something I really like. I'm kind of enjoying sinking into this more noirish feel for this one. It's been good.''
