Behati Prinsloo is relaxed about her wedding plans.

The 24-year-old model got engaged to Maroon 5 frontman Adam Levine last weekend and while the couple are excited, they haven't started thinking about their big day yet.

She told Us Weekly: ''I'm so laid back - my mind has been going but we haven't talked about anything! We're just so excited in this moment! I'm like, 'Yikes!' ''

Behati is adjusting to being engaged and admitted she is still surprised when she sees her ring.

She added: ''I forgot I slept with [the ring] on last night, and I woke up and went, 'Oh, hello!' ''

Adam and Behati - who first began dating in May 2012 and split earlier this year - surprised everyone with their engagement as Adam, 34, was spotted on holiday with Sports Illustrated swimsuit model Nina Agdal last month.

However, the romance was short-lived because Adam was still besotted with Namibian born model Behati.

An insider said: ''The Nina thing was not that serious and was not going to last. After Adam broke up with Behati, he couldn't stop thinking about her. He knew he really loved her and wanted to be with her.''

Announcing the engagement, Adam's representative said: ''Adam Levine and his girlfriend Behati Prinsloo are excited to announce they are engaged to be married.

''The couple recently reunited and Adam proposed this weekend in Los Angeles.''
