The Russian leg of her tour was cancelled due to visa issues.

So with a bit of time off to sight-see around Italy, it seems Selena Gomez found plenty of fun and fancy things to do on Friday – requiring three different outfits in total.

The 21-year-old star spent the day splashing out at the flagship Versace boutique in Milan and wading through seas of fans, before dolling up for a glamorous night out with Donatella herself.

‘To be great, learn from the greatest,’ Selena said as she uploaded a glowing snap of herself and Donatella Versace as they enjoyed a beverage and a giggle together in Milan.

As she enjoyed a night out with one of the biggest names in fashion, the pop star wore a slinky black strap cut-out dress, flattering her petite body beautifully.

But earlier in the day it was a much different story for Selena who trotted about the Italian city in jeans as she greeted her adoring fans.

Upping the glamour: Selena wore heavy eye makeup and dark lips for her night out

Tying her brunette locks into a loose top knot, the former Disney princess sported large gold hoop earrings as she hid her highly recognisable face behind a pair of dark sunglasses.

The popstrel donned a tight mid-riff baring top as she stomped around in stiletto pumps.

Completing her look was a trendy pair of ripped boy jeans that she cuffed around her ankles, adding a youthful touch to her confidently sexy ensemble.

Salute: The Come And Get It singer waved to her fans outside of her hotel

Meanwhile, the Come & Get It singer was scheduled to host a pair of shows later this month, but Russian officials turned down her visa application, forcing her to cancel the concerts.

Their reason for the refusal is reportedly fear that the star will follow in the footsteps of Madonna and Lady Gaga and speak out about gay rights during the show.

Selena had been set to play at St. Petersburg’s Ice Palace on September 23 and Moscow’s Olimiisky stadium on September 25, but a rep told E! News that she will no longer be attending.

Hands full: Selena looked to have had a successful day of retail therapy

Russian conservatives attempted to file lawsuits against both of those pop phenomena in the spirit of the controversial and vaguely worded law banning the promotion of ‘nontraditional sexual relationships’ to minors, which Russia adopted in June, reported the Moscow Times.

The Material Girl and the Poker Face singers each gave very public shout outs in 2012 against the laws to show their support of the LBGT community, leading to the threat of prosecution by the former Eastern Bloc government.

But Selena may have had other things to occupy her thoughts as she perused the various shops in the city of Milan.

Squeezed in: Selena almost disappeared in the sea of fans

She made headlines in June when she flirted with teen idol George Shelley during an interview.

And now it seems Gomez is dating the Union J singer as the two enjoyed a romantic evening in Portugal together last week.

According to The Sun, the Spring Breakers star flew out young George along with his bandmates to be the opening act for her performance in Portugal on Wednesday last week.

The paper reports that after the sold out show Gomez spent the evening with Shelley alone in her hotel room.

‘Everyone else left the room at 2 a.m. so they were able to spend the night together,’ a source told the publication.

The insider went on to reveal that Shelley actually missed his return flight the following morning with his bandmates.

But the source claims: ‘Nobody was annoyed with George. After all, he’s been pursued by one of the biggest pop stars in the world,’

Adding: ‘It’s any lad’s dream come true.’

In June the in-demand star publicly flirted with Shelley in a pre-taped appearance on CBBC’s Download.

‘I was in London for a bit and I’m actually really bummed I missed you,’ Selena said addressing the Brit. ‘So next time, maybe give me a call?’

Meanwhile, Selena will be heading to Dubai to perform on September 27, and revealed her excited on Twitter. ‘Dubai Music Week I’m comin.. :)’ she tweeted on Sunday.

The star-studded event comes hot on the heels of her European tour, which sent Justin Bieber’s ex-girlfriend to Spain, Germany, Lisbon, Paris and Belgium.
