Cara Delevingne and Michelle Rodriguez are planning to attend their first music festival together.

The 21-year-old model and the 'Machete Kills' actress have been inseparable over the past few months, and they're now keen to make their relationship even more public by attending Coachella in California as a couple next month.

A source told The Sun newspaper: ''Cara and Michelle are getting more and more serious.

''They've already been away as a couple to Thailand and now want to go to their first festival together.

''Cara is a big festival-goer and this is a dry run for Glastonbury. She loves the Somerset event and wants to take Michelle this year to experience it too.''

The pair first sparked rumours they were dating after they were spotted cuddling up to each other while watching the New York Knicks defeat the Detroit Pistons at Madison Square Garden back in January.

It is now believed Cara - who was once romantically linked to One Direction hunk Harry Styles - is so smitten with the 35-year-old star that she wants to tie the knot with her at the Niagara Falls in Canada.

A source said previously: ''It's typical of Cara to want to do something crazy and impulsive. But she seems deadly serious.

''They've talked about what kind of big day they'd have. Cara says she wants them to wed in their own element with no priest or anyone with a religious background.''
