Miley & Patrick Kiss
Miley Cyrus and Patrick Schwarzenegger pack on PDA.
Miley Cyrus and Patrick Schwarzenegger have already heated things up in 2015!

The newly rekindled duo rang in the New Year together on a high note–and no we’re not talking drugs.  Unafraid of sharing their romance with the world, they posted several photos together, one of which even shows them smooching as the clock strikes midnight.

“2015,” Miley captioned her very first photo of the new year, landing a big kiss on her BF’s lips.

The couple reportedly celebrated the night in Las Vegas alongside Patrick’s father Arnold Schwarzenegger and his girlfriend Heather Milligan.  Also in attendance?  Newly-engaged Sofia Vergara and her fiancé Joe Manganiello!

According to E! News, the couples kicked off the night with a big dinner at Strip House Las Vegas inside the Planet Hollywood Resort & Casino.

Sofia took to her Instagram to share a photo from the dinner, captioned the group pic: “Excited for the new year!!!! Wishing everyone a lot of work and happyness!!!)”

The couples then headed to the sold-out Britney Spears concert in the same hotel, meeting the Princess of Pop beforehand and singing and dancing the night away.

“Sofia and Joe were very affectionate, holding hands and whispering in each other’s ears the whole time,” an eyewitness tells E!.  Patrick and Miley also appeared to have a blast while sitting a few tables away from the pair.
