Did she lose the keys to her car? Lady Gaga wears skimpy tank top to ride her HORSE to Malibu market where she picks up green smoothie 

Lady Gaga grew up in New York City, but it appears she is going country these days.

On Sunday the 30-year-old blonde hit maker took her white horse to the Malibu Country Mart to pick up a green smoothie.

The horse was a gift from her record label Interscope.

Giddy up: Lady Gaga was seen on her white horse in Malibu on Sunday

The Poker Face hit maker did not appear to be alone as there was a male on a brown horse next to her.

The two were seen leading their animals through a busy parking lot that had BMWs and Audis.

Gaga looked like a pro as she used one hand to control the reins of the horse and the other to hold her green smoothie.

The Born This Way crooner wore a tight black tank top that had spaghetti straps and there seemed to be no bra for support.

Gaga added matching black leggings and a pair of short boots.

Her blonde locks were pulled into a small bun and the star was makeup free with only a pair of sunglasses on. 

It was odd to see the mega performer take her horse on sidewalks and on streets as that could not have been very comfortable for the horse or the singer.

But there she was weaving among the vehicles.

Asking too much? Surprisingly the star's instrument did not sell, though it was expected to bring in between $100k to $200k

Her pang for a healthy beverage must have been strong to get off the trails of Malibu. 

This sighting comes after it was revealed her childhood piano has failed to sell at auction.

The Oscar nominee's old instrument had been expected to sell for $100k  to $200k when it went under the hammer at the Hard Rock Cafe New York on Saturday, as reported by Page Six.

The fiancee of Taylor Kinney had used the piano to write her first song at the age of just five, and was selling it as part of Los Angeles-based auctioneers Julien's Auction's Music Icons memorabilia sale.

However, it failed to meet the reserve price - the lowest amount a seller will accept for their lot - and so it did not sell. 

She's evolved: She spent hours practicing on her childhood piano when she was younger, and now puts those skills to good use, as seen here in her hauntingly beautiful performance of Til It Happens To You at the 88th Oscars in February

A spokesperson for the auction house wouldn't reveal the minimum it could have changed hands for though. 

It is not yet clear whether the instrument will sell.

While Gaga's piano wasn't a hit at the auction, over 85 items which had previously belonged to Elvis Presley did prove popular.

One example was a 1969 Gibson Dove guitar that the late singer's father had made for him, which fetched a huge $334,000.

Meanwhile, Lady Gaga - whose real name is Stefani Germanotta - previously spoke of how she began learning to play the piano when she was just four years old.

For a good cause: The star showed off a smile earlier this month as she launched her and Elton John's Love Bravery collection with Macy's, from which 25 per cent goes to Elton John AIDS Foundation and her Born This Way Foundation

Her parents had taught her to be disciplined by insisting that she attended the lessons they organized, as well as by practicing regularly. 

Discussing how she felt 'isolated' and 'lonely' as a child, she said: 'I did feel very isolated as a young person, and not because I was alone or abandoned by my family, it's just a chemical thing.'

'Some kids are born like that. We don't know why we feel lonely, but we do. It's like depression but it's not because someone neglected me. I grew up in a very disciplined household.'

Lady Gaga continued: 'I played piano when I was four. I sat at it and I started to play it. Did my parents then say to me that we are giving you lessons? Yes.'

'And then when I tried to stop playing they said, 'You can sit there for an hour and practice, or you can sit there for two and not practice.''
