‘The Big Bang Theory’ Star Johnny Galecki Dating Reality Show Competitor With Prostitute Grandmother

Johnny Galecki has found love again.

The Big Bang Theory star is allegedly dating The X Factor UK competitor Katie Waissel. NOW Magazine claims that 38-year-old Johnny Galecki and the 28-year-old reality show star have been secretly dating for a few weeks.

A source told the magazine that things are “going really well” for the new couple, but they’re being careful to keep their relationship out of the tabloids.

“Johnny is really private and Katie isn’t one to splash her love life around so they have been keeping a low profile.”

The duo’s first date reportedly took place a few weeks ago at the Chateau Marmont in Los Angeles. Johnny Galecki was spotted sneaking out to Katie Waissel’s car and unsuccessfully attempting to hide in the backseat.

As The Inquisitr previously reported, Galecki’s last relationship was with Pan Am actress Kelli Garner. News of their split broke late in August, with reports saying that the breakup was amicable. Johnny has also dated his Big Bang Theory costars Kaley Cuoco and Sara Gilbert.

Johnny Galecki and Katie Waissel are just casually dating right now, but the source told NOW that this relationship will probably become something more than a quick rebound fling for Galecki.

“Johnny and Katie are both down to earth and spend most of their time together laughing. It’s early days but could develop into something serious.”

Waissel seemed to reference her relationship with Galecki in a tweet about having the best boyfriend in the world.

Katie competed on The X Factor UK in 2010 before moving to Los Angeles. She continues to make music with her rock band, Red Velvet. Waissel married model Brad Alphonso in 2012, but the couple split after just two months of marriage. Katie said that she decided to end things after a series of “horrific” fights.

Katie Waissel resembles Kaley Cuoco with her blonde locks and cute face, and she’s a fan of Instagram just like Johnny Galecki’s ex. However, she’s a bit of a wild child who has a rocker chick sense of style, and she has more than a few tattoos. She recently showed off a few of them in a sexy Fifty Shades of Grey-inspired Instagram photo.

Katie also likes to take butt selfies. She explained that she’s more likely to do this after drinking in the caption for the photo below.

“Thank you #Christmas for making my ass huge!! Kim Kardashian eat your heart out haha!!! #ass #dontpostpicswhenyouvehadwine!!!”

Like Miley Cyrus, Waissel loves to stick her tongue out in photos.

According to the Daily Mail, Waissel’s grandmother, Sheila Vogel, made headlines in the UK after it was revealed that the 81-year-old was working as a prostitute for a company called Vintage Vamps. Vogel also starred in an adult movie titled The Great British Granny Bang.

The octogenarian escort complained that Katie’s X Factor notoriety ruined her career.

“Katie joined the X Factor and went to the press. She has ruined my career. I’m afraid she has. But I still wish her well and I love her.”
