It has been previously reported that Miley Cyrus and her new rumored boyfriend Patrick Schwarzenegger, the son of famous actor Arnold Schwarzenegger with Maria Shriver are really into each other.

Although, both are keeping mum about their said relationship, a number of photos of them kissing and cuddling in different occassions have been published online, a strong indication that they are more than just friends.

Most recently Miley and Patrick were spotted at MAC Cosmetics' fund raising event for HIV/AIDS. The duo attended the premiere of the Canadian cosmetics company's documentary titled 'It's Not Over'

Miley Cyrus, the newest brand ambassador of MAC's Viva Glam line, and Arnold Schwarzenegger's 21-year-old son watched the short film while holding hands. 

They then went to a nearby restaurant, RivaBella, to dine.

To avoid the paparazzi the couple sneaked through the back door of the pizzaria then ordered a truffle pizza and a pasta dish, according to an eyewitness.

They "were very smiley and cute with one another" and it looked like that they're really "into each other," a witness of E! News revealed.

Reportedly, Miley's relationship with Patrick is indeed serious and not just a past time thing, according to an alleged friend of the popstar.

"I have seen Miley with Liam and other boyfriends, but honestly I have never seen her look as loved-up as this," the witness told E! News. "This is more than just a fling, they look like they are falling in love with one another."

While, the public may be at shock with Miley Cyrus' new boyfriend, the two are reportedly friends for a really long time already.

"They might seem like an odd pairing, but they are quite good for each other," another source admitted recently told E! News. "They've been friends forever."

Despite rumors claiming that Patrick's famous mother and a descendant of the Kennedy's, is not happy with the budding relationship of her son and the very controversial Miley Cyrus, Maria Shriver actually "thinks Miley is a nice girl."
