Looks like Whitney Port and Ben Nemtin’s relationship really is a match made in MTV heaven.
The City starlet and The Buried Life star copped to “hanging out” last month – but lately things seem to be getting more serious.
Nemtin recently helped Port celebrate her 25th birthday during an intimate bash at the Los Angeles restaurant Cecconi’s. And when he needed to be in Chicago last weekend to film The Oprah Winfrey Show for an episode scheduled to air April 9, Port joined her beau in the Windy City.
And it wasn’t all business: The new couple kicked back at the Chicago hotspot The Underground on Saturday night. In between sips of Patron, Port chatted with – and planted kisses – on her new guy.
As the Bachelorette’s Jillian Harris and Ed Swiderski chatted with club owner Billy Dec, Port and Nemtin seemed smitten, says a source: “They were definitely flirty and affectionate.”
