All revved up: Gwen Stefani and Blake Shelton carried on with the kissing after they landed back in LA on Tuesday following a fun weekend in Colorado and then Oklahoma

Gwen stood up on tip-toe in her flip flops with her arms wrapped around Blake who had his hands planted firmly on her pert posterior.

They were both dressed casually with Gwen wearing baggy denim jeans that hung from her hips, a white tank top and a plaid shirt tied loosely around her waist.

Blake wore faded jeans with a loose-fitting black shirt and baseball cap to shade his eyes.

The 46-year-old singer shared a cosy Instagram of the pair with Blake leaning his head on her shoulder and that was followed by a very sweet tweet.

'Hi strawberry moon #honeymoon #rosemoon gx #Oklahoma 2016,' Gwen wrote on Twitter as the pair took in the captivating sight.

'Strawberry moon' is a name used by Native Americans that heralds the start of strawberry season with the appearance of a full moon, which hasn't occurred in almost 50 years, not since 1967.

'Honey moon' is used to describe the phenomenon, but that is also a term associated with June weddings.

Gwen, no doubt, had her fans wondering if she had marriage on her mind when she looked up at that 'honey moon' with Blake.

The couple spent an adventurous day in Oklahoma on Monday that included a boat ride on Lake Texoma and a drive through Blake's corn fields.
